Struct prost_types::compiler::CodeGeneratorRequest

pub struct CodeGeneratorRequest {
    pub file_to_generate: Vec<String>,
    pub parameter: Option<String>,
    pub proto_file: Vec<FileDescriptorProto>,
    pub compiler_version: Option<Version>,
}

An encoded CodeGeneratorRequest is written to the plugin’s stdin.

Fields

file_to_generate: Vec<String>

The .proto files that were explicitly listed on the command-line. The code generator should generate code only for these files. Each file’s descriptor will be included in proto_file, below.

parameter: Option<String>

The generator parameter passed on the command-line.

proto_file: Vec<FileDescriptorProto>

FileDescriptorProtos for all files in files_to_generate and everything they import. The files will appear in topological order, so each file appears before any file that imports it.

protoc guarantees that all proto_files will be written after the fields above, even though this is not technically guaranteed by the protobuf wire format. This theoretically could allow a plugin to stream in the FileDescriptorProtos and handle them one by one rather than read the entire set into memory at once. However, as of this writing, this is not similarly optimized on protoc’s end – it will store all fields in memory at once before sending them to the plugin.

Type names of fields and extensions in the FileDescriptorProto are always fully qualified.

compiler_version: Option<Version>

The version number of protocol compiler.

Implementations

impl CodeGeneratorRequest

pub fn parameter(&self) -> &str

Returns the value of parameter, or the default value if parameter is unset.

Trait Implementations

impl Clone for CodeGeneratorRequest

fn clone(&self) -> CodeGeneratorRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CodeGeneratorRequest

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

Formats the value using the given formatter.

impl Default for CodeGeneratorRequest

fn default() -> Self

Returns the “default value” for a type.

impl Message for CodeGeneratorRequest

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

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

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

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

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

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

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for CodeGeneratorRequest

fn eq(&self, other: &CodeGeneratorRequest) -> 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.
