Fields

name: Option<String>

file name, relative to root of source tree

Field 1: name

package: Option<String>

e.g. “foo”, “foo.bar”, etc.

Field 2: package

dependency: Vec<String>

Names of files imported by this file.

Field 3: dependency

public_dependency: Vec<i32>

Indexes of the public imported files in the dependency list above.

Field 10: public_dependency

weak_dependency: Vec<i32>

Indexes of the weak imported files in the dependency list. For Google-internal migration only. Do not use.

Field 11: weak_dependency

option_dependency: Vec<String>

Names of files imported by this file purely for the purpose of providing option extensions. These are excluded from the dependency list above.

Field 15: option_dependency

message_type: Vec<DescriptorProto>

All top-level definitions in this file.

Field 4: message_type

enum_type: Vec<EnumDescriptorProto>

Field 5: enum_type

service: Vec<ServiceDescriptorProto>

Field 6: service

extension: Vec<FieldDescriptorProto>

Field 7: extension

options: MessageField<FileOptions>

Field 8: options

source_code_info: MessageField<SourceCodeInfo>

This field contains optional information about the original source code. You may safely remove this entire field without harming runtime functionality of the descriptors – the information is needed only by development tools.

Field 9: source_code_info

syntax: Option<String>

The syntax of the proto file. The supported values are “proto2”, “proto3”, and “editions”.

If edition is present, this value must be “editions”. WARNING: This field should only be used by protobuf plugins or special cases like the proto compiler. Other uses are discouraged and developers should rely on the protoreflect APIs for their client language.

Field 12: syntax

edition: Option<Edition>

The edition of the proto file. WARNING: This field should only be used by protobuf plugins or special cases like the proto compiler. Other uses are discouraged and developers should rely on the protoreflect APIs for their client language.

Field 14: edition

Implementations

impl FileDescriptorProto

pub const TYPE_URL: &'static str = "type.googleapis.com/google.protobuf.FileDescriptorProto"

Protobuf type URL for this message, for use with Any::pack and Any::unpack_if.

Format: type.googleapis.com/<fully.qualified.TypeName>

Trait Implementations

impl Clone for FileDescriptorProto

fn clone(&self) -> FileDescriptorProto

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileDescriptorProto

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FileDescriptorProto

fn default() -> FileDescriptorProto

Returns the “default value” for a type.

impl DefaultInstance for FileDescriptorProto

fn default_instance() -> &'static Self

Return a reference to the single default instance of this type.

impl ExtensionSet for FileDescriptorProto

const PROTO_FQN: &'static str = "google.protobuf.FileDescriptorProto"

Fully-qualified proto type name of this message (no leading dot), e.g. "google.protobuf.FieldOptions".

fn unknown_fields(&self) -> &UnknownFields

Immutable access to the extendee’s unknown-field storage.

fn unknown_fields_mut(&mut self) -> &mut UnknownFields

Mutable access to the extendee’s unknown-field storage.

fn extension<C>(&self, ext: &Extension<C>) -> <C as ExtensionCodec>::Output

where C: ExtensionCodec,

Read an extension value.

fn set_extension<C>( &mut self, ext: &Extension<C>, value: <C as ExtensionCodec>::Value, )

where C: ExtensionCodec,

Write an extension value, replacing any prior occurrences.

fn has_extension<C>(&self, ext: &Extension<C>) -> bool

where C: ExtensionCodec,

Returns true if any record at the extension’s field number is present.

fn clear_extension<C>(&mut self, ext: &Extension<C>)

where C: ExtensionCodec,

Remove all records at the extension’s field number.

fn extension_or_default<C>( &self, ext: &Extension<C>, ) -> <C as ExtensionCodec>::Value

where C: ExtensionCodec<Output = Option<<C as ExtensionCodec>::Value>>, <C as ExtensionCodec>::Value: Default,

Read a singular extension value, returning the proto2 [default = ...] value if absent, or the type’s Default if no proto default was declared.

impl Message for FileDescriptorProto

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

Returns the total encoded size in bytes.

The result is a u32; the protobuf specification requires all messages to fit within 2 GiB (2,147,483,647 bytes), so a compliant message will never overflow this type.

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

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, depth: u32, ) -> 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 BufMut)

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

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

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

fn encoded_len(&self) -> u32

Compute the encoded byte size of this message.

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

Encode this message as a length-delimited byte sequence.

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

Encode this message to a new Vec<u8>.

fn encode_to_bytes(&self) -> Bytes

Encode this message to a new bytes::Bytes.

fn decode(buf: &mut impl Buf) -> Result<Self, DecodeError>

where Self: Sized,

Decode a message from a buffer.

fn decode_from_slice(data: &[u8]) -> Result<Self, DecodeError>

where Self: Sized,

Decode a message from a byte slice.

fn decode_length_delimited(buf: &mut impl Buf) -> Result<Self, DecodeError>

where Self: Sized,

Decode a length-delimited message from a buffer.

fn merge_to_limit( &mut self, buf: &mut impl Buf, depth: u32, limit: usize, ) -> Result<(), DecodeError>

Merge fields from a buffer until buf.remaining() reaches limit.

fn merge_group( &mut self, buf: &mut impl Buf, depth: u32, field_number: u32, ) -> Result<(), DecodeError>

Merges a group-encoded message from buf, reading fields until an EndGroup tag with the given field_number is encountered.

fn merge(&mut self, buf: &mut impl Buf, depth: u32) -> Result<(), DecodeError>

Merge fields from a buffer into this message.

fn merge_from_slice(&mut self, data: &[u8]) -> Result<(), DecodeError>

Merge fields from a byte slice into this message.

fn merge_length_delimited( &mut self, buf: &mut impl Buf, depth: u32, ) -> Result<(), DecodeError>

Merge fields from a length-delimited sub-message payload into this message.

impl PartialEq for FileDescriptorProto

fn eq(&self, other: &FileDescriptorProto) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
