Struct Api 

pub struct Api {
    pub name: String,
    pub methods: Vec<Method>,
    pub options: Vec<Option>,
    pub version: String,
    pub source_context: MessageField<SourceContext, Inline<SourceContext>>,

    pub syntax: EnumValue<Syntax>,
    pub edition: String,
    /* private fields */
}

Api is a light-weight descriptor for an API Interface.

Interfaces are also described as “protocol buffer services” in some contexts, such as by the “service” keyword in a .proto file, but they are different from API Services, which represent a concrete implementation of an interface as opposed to simply a description of methods and bindings. They are also sometimes simply referred to as “APIs” in other contexts, such as the name of this message itself. See https://cloud.google.com/apis/design/glossary for detailed terminology.

New usages of this message as an alternative to ServiceDescriptorProto are strongly discouraged. This message does not reliability preserve all information necessary to model the schema and preserve semantics. Instead make use of FileDescriptorSet which preserves the necessary information.

Fields

name: String

The fully qualified name of this interface, including package name followed by the interface’s simple name.

Field 1: name

methods: Vec<Method>

The methods of this interface, in unspecified order.

Field 2: methods

options: Vec<Option>

Any metadata attached to the interface.

Field 3: options

version: String

A version string for this interface. If specified, must have the form major-version.minor-version, as in 1.10. If the minor version is omitted, it defaults to zero. If the entire version field is empty, the major version is derived from the package name, as outlined below. If the field is not empty, the version in the package name will be verified to be consistent with what is provided here.

The versioning schema uses [semantic versioning](http://semver.org) where the major version number indicates a breaking change and the minor version an additive, non-breaking change. Both version numbers are signals to users what to expect from different versions, and should be carefully chosen based on the product plan.

The major version is also reflected in the package name of the interface, which must end in v<major-version>, as in google.feature.v1. For major versions 0 and 1, the suffix can be omitted. Zero major versions must only be used for experimental, non-GA interfaces.

Field 4: version

source_context: MessageField<SourceContext, Inline<SourceContext>>

Source context for the protocol buffer service represented by this message.

Field 5: source_context

mixins: Vec<Mixin>

Included interfaces. See Mixin.

Field 6: mixins

syntax: EnumValue<Syntax>

The source syntax of the service.

Field 7: syntax

edition: String

The source edition string, only valid when syntax is SYNTAX_EDITIONS.

Field 8: edition

impl Message for Api

fn compute_size(&self, __cache: &mut SizeCache) -> u32

Returns the total encoded size in bytes.

Accumulates in u64 (which cannot overflow for in-memory data) and saturates to u32 at return, so a message whose encoded size exceeds the 2 GiB protobuf limit yields a value above ::buffa::MAX_MESSAGE_BYTES that the encode entry points reject, never a silently wrapped size.

fn write_to(&self, __cache: &mut SizeCache, buf: &mut impl EncodeSink)

Write this message’s encoded bytes to a buffer, consuming nested-message sizes from cache (populated by a prior compute_size call on the same cache).

fn merge_field( &mut self, tag: Tag, buf: &mut impl Buf, ctx: DecodeContext<'_>, ) -> Result<(), DecodeError>

Processes a single already-decoded tag and its associated field data from buf.

fn clear(&mut self)

Clear all fields to their default values.

fn encode(&self, buf: &mut impl EncodeSink)

Compute size, then write. This is the primary encoding API.

fn try_encode(&self, buf: &mut impl EncodeSink) -> Result<(), EncodeError>

Encode, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_with_cache(&self, cache: &mut SizeCache, buf: &mut impl EncodeSink)

Encode using a caller-supplied SizeCache, for reuse across many encodes in a hot loop. Clears the cache first.

fn try_encode_with_cache( &self, cache: &mut SizeCache, buf: &mut impl EncodeSink, ) -> Result<(), EncodeError>

Encode with a caller-supplied SizeCache, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES). Clears the cache first.

fn try_encode_bounded( &self, max_bytes: u32, buf: &mut impl EncodeSink, ) -> Result<u32, EncodeError>

Encode this message into buf only if its encoded size fits within max_bytes, using a single size pass that is then reused for the write.

fn try_encode_bounded_with_cache( &self, max_bytes: u32, cache: &mut SizeCache, buf: &mut impl EncodeSink, ) -> Result<u32, EncodeError>

Like try_encode_bounded but reuses an existing SizeCache, clearing it first.

fn encoded_len(&self) -> u32

Compute the encoded byte size of this message.

fn try_encoded_len(&self) -> Result<u32, EncodeError>

Compute the encoded byte size, returning an error instead of panicking if it exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_length_delimited(&self, buf: &mut impl EncodeSink)

Encode this message as a length-delimited byte sequence.

fn try_encode_length_delimited( &self, buf: &mut impl EncodeSink, ) -> Result<(), EncodeError>

Encode as a length-delimited byte sequence, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_to_vec(&self) -> Vec<u8>

Encode this message to a new Vec<u8>.

fn try_encode_to_vec(&self) -> Result<Vec<u8>, EncodeError>

Encode to a new Vec<u8>, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_to_bytes(&self) -> Bytes

Encode this message to a new bytes::Bytes.

fn try_encode_to_bytes(&self) -> Result<Bytes, EncodeError>

Encode to a new bytes::Bytes, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).
