构建 Rust Protos

Cargo

有关如何设置构建的示例，请参阅 protobuf-example crate。

Bazel

为 Protobuf 定义构建 Rust 库的过程与其他编程语言类似

1. 使用与语言无关的 proto_library 规则

   proto_library(
       name = "person_proto",
       srcs = ["person.proto"],
   )
   

2. 创建一个 Rust 库

   load("//third_party/protobuf/rust:defs.bzl", "rust_proto_library")
   
   proto_library(
       name = "person_proto",
       srcs = ["person.proto"],
   )
   
   rust_proto_library(
       name = "person_rust_proto",
       deps = [":person_proto"],
   )
   

3. 通过将其包含在 Rust 二进制文件中来使用该库

   load("//third_party/bazel_rules/rules_rust/rust:defs.bzl", "rust_binary")
   load("//third_party/protobuf/rust:defs.bzl", "rust_proto_library")
   
   proto_library(
       name = "person_proto",
       srcs = ["person.proto"],
   )
   
   rust_proto_library(
       name = "person_rust_proto",
       deps = [":person_proto"],
   )
   
   rust_binary(
       name = "greet",
       srcs = ["greet.rs"],
       deps = [
           ":person_rust_proto",
       ],
   )
