構建 Rust Protos

Cargo

請參閱 protobuf-example crate，瞭解如何設定構建的示例。

Bazel

為 Protobuf 定義構建 Rust 庫的過程與其他程式語言類似

1. 使用與語言無關的 proto_library 規則

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

2. 建立一個 Rust 庫

   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. 透過將其包含在 Rust 二進位制檔案中來使用該庫

   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",
       ],
   )
