Crate prost_wkt_types

prost-wkt adds helper methods to deal with protobuf well known types.

Modules

value

Nested message and enum types in Value.

Structs

Any

Any contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message.

AnyError

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.

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:

FieldMask

FieldMask represents a set of symbolic field paths, for example:

ListValue

ListValue is a wrapper around a repeated field of values.

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.

Timestamp

A Timestamp represents a point in time independent of any time zone or local calendar, encoded as a count of seconds and fractions of seconds at nanosecond resolution. The count is relative to an epoch at UTC midnight on January 1, 1970, in the proleptic Gregorian calendar which extends the Gregorian calendar backwards to year one.

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 that variants, absence of any variant indicates an error.

ValueError

Enums

DurationError

A duration handling error.

NullValue

NullValue is a singleton enumeration to represent the null value for the Value type union.

TimestampError

A timestamp handling error.

Traits

MessageSerde

Trait to support serialization and deserialization of prost messages.
