Crate ttrpc_codegen 

Pure-Rust build-time code generation for ttrpc services.

ttrpc-codegen parses .proto files and generates Protocol Buffers messages, typed ttrpc clients, server traits, and registration helpers. It does not require a protoc executable.

Add this crate under [build-dependencies] and invoke Codegen from build.rs.

Examples

use ttrpc_codegen::{Codegen, Customize, ProtobufCustomize};

Codegen::new()
    .out_dir(std::env::var("OUT_DIR").expect("OUT_DIR is set for build scripts"))
    .input("proto/greeter.proto")
    .include("proto")
    .rust_protobuf()
    .customize(Customize {
        async_all: true,
        gen_mod: true,
        ..Default::default()
    })
    .rust_protobuf_customize(ProtobufCustomize::default().gen_mod_rs(true))
    .run()?;

When no output directory is configured, Codegen::run uses Cargo’s OUT_DIR environment variable. Generated module declarations can then be included with:

include!(concat!(env!("OUT_DIR"), "/mod.rs"));

Structs

Codegen

Builder for pure-Rust Protocol Buffers and ttrpc code generation.

Customize

Customize generated code.

ProtobufCustomize

Specifies style of generated code. Generated files can be customized using this proto or using rustproto.proto options.

Traits

ProtobufCustomizeCallback

Dynamic callback to customize code generation.
