CheckpointCommitment
A commitment made by a checkpoint.
CheckpointSummary
A header for a checkpoint on the Sui blockchain.
On the Sui network, checkpoints define the history of the blockchain. They are quite similar to the concept of blocks used by other blockchains like Bitcoin or Ethereum. The Sui blockchain, however, forms checkpoints after transaction execution has already happened to provide a certified history of the chain, instead of being formed before execution.
Checkpoints commit to a variety of state, including but not limited to:
- The hash of the previous checkpoint.
- The set of transaction digests, their corresponding effects digests, as well as the set of user signatures that authorized its execution.
- The objects produced by a transaction.
- The set of live objects that make up the current state of the chain.
- On epoch transitions, the next validator committee.
CheckpointSummarys themselves don't directly include all of the previous information but they
are the top-level type by which all the information is committed to transitively via cryptographic
hashes included in the summary. CheckpointSummarys are signed and certified by a quorum of
the validator committee in a given epoch to allow verification of the chain's state.
CheckpointSummary. This will be None only for the first, or genesis, checkpoint.CheckpointSummary is not an evolvable structure - it must be readable by any version of the code. Therefore, to allow extensions to be added to CheckpointSummary, opaque data can be added to checkpoints, which can be deserialized based on the current protocol version.EndOfEpochData
Data, which when included in a CheckpointSummary, signals the end of an Epoch.

QuotaFailure
Describes how a quota check failed.
For example if a daily limit was exceeded for the calling project,
a service could respond with a QuotaFailure detail containing the project

Describes the resource that is being accessed.
writer permission on the developer console project.user:<owner email> or project:<Google developer project id>.RetryInfo
Describes when the clients can retry a failed request. Clients could ignore the recommendation here or retry when this information is missing from error responses.
It's always recommended that clients should use exponential backoff when retrying.
Clients should wait until retry_delay amount of time has passed since
receiving the error response before retrying. If retrying requests also
fail, clients should use an exponential backoff scheme to gradually increase
the delay between retries based on retry_delay, until either a maximum
number of retries have been reached or a maximum retry delay cap has been
reached.

Messages
Status
The Status type defines a logical error model that is suitable for
different programming environments, including REST APIs and RPC APIs. It is
used by gRPC. Each Status message contains
three pieces of data: error code, error message, and error details.
You can find out more about this error model and how to work with it in the API Design Guide.
google/protobuf/struct.proto
Messages
ListValue
ListValue is a wrapper around a repeated field of values.
The JSON representation for ListValue is JSON array.
Struct
Struct represents a structured data value, consisting of fields
which map to dynamically typed values. In some languages, Struct
might be supported by a native representation. For example, in
scripting languages like JS a struct is represented as an
object. The details of that representation are described together
with the proto support for the language.
The JSON representation for Struct is JSON object.
FieldsEntry
Value
Value represents a dynamically typed value which can be either
null, a number, a string, a boolean, a recursive struct value, or a
list of values. A producer of value is expected to set one of these
variants. Absence of any variant indicates an error.
The JSON representation for Value is JSON value.
Value.Enums
NullValue
NullValue is a singleton enumeration to represent the null value for the Value type union. The JSON representation for NullValue is JSON null.NULL_VALUEgoogle/protobuf/field_mask.proto
Messages
FieldMask
FieldMask represents a set of symbolic field paths, for example:
paths: "f.a" paths: "f.b.d"
Here f represents a field in some root message, a and b
fields in the message found in f, and d a field found in the
message in f.b.
Field masks are used to specify a subset of fields that should be returned by a get operation or modified by an update operation. Field masks also have a custom JSON encoding (see below).
Field Masks in Projections
When used in the context of a projection, a response message or sub-message is filtered by the API to only contain those fields as specified in the mask. For example, if the mask in the previous example is applied to a response message as follows:
f { a : 22 b { d : 1 x : 2 } y : 13 } z: 8
The result will not contain specific values for fields x,y and z (their value will be set to the default, and omitted in proto text output):
f { a : 22 b { d : 1 } }
A repeated field is not allowed except at the last position of a paths string.
If a FieldMask object is not present in a get operation, the operation applies to all fields (as if a FieldMask of all fields had been specified).
Note that a field mask does not necessarily apply to the top-level response message. In case of a REST get operation, the field mask applies directly to the response, but in case of a REST list operation, the mask instead applies to each individual message in the returned resource list. In case of a REST custom method, other definitions may be used. Where the mask applies will be clearly documented together with its declaration in the API. In any case, the effect on the returned resource/resources is required behavior for APIs.
Field Masks in Update Operations
A field mask in update operations specifies which fields of the targeted resource are going to be updated. The API is required to only change the values of the fields as specified in the mask and leave the others untouched. If a resource is passed in to describe the updated values, the API ignores the values of all fields not covered by the mask.
If a repeated field is specified for an update operation, new values will
be appended to the existing repeated field in the target resource. Note that
a repeated field is only allowed in the last position of a paths string.
If a sub-message is specified in the last position of the field mask for an update operation, then new value will be merged into the existing sub-message in the target resource.
For example, given the target message:
f { b { d: 1 x: 2 } c: [1] }
And an update message:
f { b { d: 10 } c: [2] }
then if the field mask is:
paths: ["f.b", "f.c"]
then the result will be:
f { b { d: 10 x: 2 } c: [1, 2] }
An implementation may provide options to override this default behavior for repeated and message fields.
In order to reset a field's value to the default, the field must be in the mask and set to the default value in the provided resource. Hence, in order to reset all fields of a resource, provide a default instance of the resource and set all fields in the mask, or do not provide a mask as described below.
If a field mask is not present on update, the operation applies to all fields (as if a field mask of all fields has been specified). Note that in the presence of schema evolution, this may mean that fields the client does not know and has therefore not filled into the request will be reset to their default. If this is unwanted behavior, a specific service may require a client to always specify a field mask, producing an error if not.
As with get operations, the location of the resource which describes the updated values in the request message depends on the operation kind. In any case, the effect of the field mask is required to be honored by the API.
Considerations for HTTP REST
The HTTP kind of an update operation which uses a field mask must be set to PATCH instead of PUT in order to satisfy HTTP semantics (PUT must only be used for full updates).
JSON Encoding of Field Masks
In JSON, a field mask is encoded as a single string where paths are separated by a comma. Fields name in each path are converted to/from lower-camel naming conventions.
As an example, consider the following message declarations:
message Profile { User user = 1; Photo photo = 2; } message User { string display_name = 1; string address = 2; }
In proto a field mask for Profile may look as such:
mask { paths: "user.display_name" paths: "photo" }
In JSON, the same mask is represented as below:
{ mask: "user.displayName,photo" }
Field Masks and Oneof Fields
Field masks treat fields in oneofs just as regular fields. Consider the following message:
message SampleMessage { oneof test_oneof { string name = 4; SubMessage sub_message = 9; } }
The field mask can be:
mask { paths: "name" }
Or:
mask { paths: "sub_message" }
Note that oneof type names ("test_oneof" in this case) cannot be used in paths.
Field Mask Verification
The implementation of any API method which has a FieldMask type field in the
request should verify the included field paths, and return an
INVALID_ARGUMENT error if any path is unmappable.

Timestamp
A Timestamp represents a point in time independent of any time zone
or calendar, represented as seconds and fractions of seconds at
nanosecond resolution in UTC Epoch time. It is encoded using the
Proleptic Gregorian Calendar which extends the Gregorian calendar
backwards to year one. It is encoded assuming all minutes are 60
seconds long, i.e. leap seconds are "smeared" so that no leap second
table is needed for interpretation. Range is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z.
Restricting to that range ensures that conversion to
and from RFC 3339 date strings is possible.
See https://www.ietf.org/rfc/rfc3339.txt.
Examples
Example 1: Compute Timestamp from POSIX time().
Timestamp timestamp;
timestamp.set_seconds(time(NULL));
timestamp.set_nanos(0);
Example 2: Compute Timestamp from POSIX gettimeofday().
struct timeval tv;
gettimeofday(&tv, NULL);
Timestamp timestamp;
timestamp.set_seconds(tv.tv_sec);
timestamp.set_nanos(tv.tv_usec * 1000);
Example 3: Compute Timestamp from Win32 GetSystemTimeAsFileTime().
FILETIME ft;
GetSystemTimeAsFileTime(&ft);
UINT64 ticks = (((UINT64)ft.dwHighDateTime) &#lt;&#lt; 32) | ft.dwLowDateTime;
// A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
// is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
Timestamp timestamp;
timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
timestamp.set_nanos((INT32) ((ticks % 10000000) * 100)); //
Example 4: Compute Timestamp from Java System.currentTimeMillis().
long millis = System.currentTimeMillis();
Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
.setNanos((int) ((millis % 1000) * 1000000)).build();
Example 5: Compute Timestamp from current time in Python.
timestamp = Timestamp()
timestamp.GetCurrentTime()
JSON Mapping
In JSON format, the Timestamp type is encoded as a string in the
RFC 3339 format. That is, the
format is {year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z
where {year} is always expressed using four digits while {month}, {day},
{hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
seconds, which can go up to 9 digits (so up to 1 nanosecond resolution),
are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
is required, though only UTC (as indicated by "Z") is presently supported.
For example, 2017-01-15T01:30:15.01Z encodes 15.01 seconds past
01:30 UTC on January 15, 2017.
In JavaScript, you can convert a Date object to this format using the
standard toISOString()
method. In Python, you can convert a standard datetime.datetime object
to this format using strftime
with the time format spec %Y-%m-%dT%H:%M:%S.%fZ. Likewise, in Java, you
can use the Joda Time's ISODateTimeFormat.dateTime()
to obtain a formatter capable of generating timestamps in this format.

Messages
Duration
A Duration represents a signed, fixed-length span of time represented as a count of seconds and fractions of seconds at nanosecond resolution. It is independent of any calendar and concepts like "day" or "month". It is related to Timestamp in that the difference between two Timestamp values is a Duration and it can be added or subtracted from a Timestamp. Range is approximately +-10,000 years.
Examples
Example 1: Compute Duration from two Timestamps in pseudo code.
Timestamp start = ...; Timestamp end = ...; Duration duration = ...;
duration.seconds = end.seconds - start.seconds; duration.nanos = end.nanos - start.nanos;
if (duration.seconds &#lt; 0 && duration.nanos > 0) { duration.seconds += 1; duration.nanos -= 1000000000; } else if (duration.seconds > 0 && duration.nanos &#lt; 0) { duration.seconds -= 1; duration.nanos += 1000000000; }
Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
Timestamp start = ...; Duration duration = ...; Timestamp end = ...;
end.seconds = start.seconds + duration.seconds; end.nanos = start.nanos + duration.nanos;
if (end.nanos &#lt; 0) { end.seconds -= 1; end.nanos += 1000000000; } else if (end.nanos >= 1000000000) { end.seconds += 1; end.nanos -= 1000000000; }
Example 3: Compute Duration from datetime.timedelta in Python.
td = datetime.timedelta(days=3, minutes=10) duration = Duration() duration.FromTimedelta(td)
JSON Mapping
In JSON format, the Duration type is encoded as a string rather than an object, where the string ends in the suffix "s" (indicating seconds) and is preceded by the number of seconds, with nanoseconds expressed as fractional seconds. For example, 3 seconds with 0 nanoseconds should be encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should be expressed in JSON format as "3.000000001s", and 3 seconds and 1 microsecond should be expressed in JSON format as "3.000001s".
seconds field and a positive or negative nanos field. For durations of one second or more, a non-zero value for the nanos field must be of the same sign as the seconds field. Must be from -999,999,999 to +999,999,999 inclusive.google/protobuf/empty.proto
Messages
Empty
A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance:
service Foo {
rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
}
google/protobuf/any.proto
Messages
Any
Any contains an arbitrary serialized protocol buffer message along with a
URL that describes the type of the serialized message.
Protobuf library provides support to pack/unpack Any values in the form of utility functions or additional generated methods of the Any type.
Example 1: Pack and unpack a message in C++.
Foo foo = ...; Any any; any.PackFrom(foo); ... if (any.UnpackTo(&foo)) { ... }
Example 2: Pack and unpack a message in Java.
Foo foo = ...; Any any = Any.pack(foo); ... if (any.is(Foo.class)) { foo = any.unpack(Foo.class); } // or ... if (any.isSameTypeAs(Foo.getDefaultInstance())) { foo = any.unpack(Foo.getDefaultInstance()); }
Example 3: Pack and unpack a message in Python.
foo = Foo(...) any = Any() any.Pack(foo) ... if any.Is(Foo.DESCRIPTOR): any.Unpack(foo) ...
Example 4: Pack and unpack a message in Go
foo := &pb.Foo{...} any, err := anypb.New(foo) if err != nil { ... } ... foo := &pb.Foo{} if err := any.UnmarshalTo(foo); err != nil { ... }
The pack methods provided by protobuf library will by default use 'type.googleapis.com/full.type.name' as the type URL and the unpack methods only use the fully qualified type name after the last '/' in the type URL, for example "foo.bar.com/x/y.z" will yield type name "y.z".
JSON
The JSON representation of an Any value uses the regular
representation of the deserialized, embedded message, with an
additional field @type which contains the type URL. Example:
package google.profile; message Person { string first_name = 1; string last_name = 2; }
{ "@type": "type.googleapis.com/google.profile.Person", "firstName": &#lt;string>, "lastName": &#lt;string> }
If the embedded message type is well-known and has a custom JSON
representation, that representation will be embedded adding a field
value which holds the custom JSON in addition to the @type
field. Example (for message [google.protobuf.Duration][]):
{ "@type": "type.googleapis.com/google.protobuf.Duration", "value": "1.212s" }
path/google.protobuf.Duration). The name should be in a canonical form (e.g., leading "." is not accepted). In practice, teams usually precompile into the binary all types that they expect it to use in the context of Any. However, for URLs which use the scheme http, https, or no scheme, one can optionally set up a type server that maps type URLs to message definitions as follows: * If no scheme is provided, https is assumed. * An HTTP GET on the URL must yield a [google.protobuf.Type][] value in binary format, or produce an error. * Applications are allowed to cache lookup results based on the URL, or have them precompiled into a binary to avoid any lookup. Therefore, binary compatibility needs to be preserved on changes to types. (Use versioned type names to manage breaking changes.) Note: this functionality is not currently available in the official protobuf release, and it is not used for type URLs beginning with type.googleapis.com. As of May 2023, there are no widely used type server implementations and no plans to implement one. Schemes other than http, https (or the empty scheme) might be used with implementation specific semantics.Scalar Value Types
