Rust Thrift library

Overview

This crate implements the components required to build a working Thrift server and client. It is divided into the following modules:

  1. errors
  2. protocol
  3. transport
  4. server
  5. autogen

The modules are layered as shown. The generated layer is code generated by the Thrift compiler's Rust plugin. It uses the components defined in this crate to serialize and deserialize types and implement RPC. Users interact with these types and services by writing their own code on top.

Using this crate

Add thrift = "x.y.z" to your Cargo.toml, where x.y.z is the version of the Thrift compiler you're using.

Compatibility

The Rust library and auto-generated code targets Rust versions 1.28+. It does not currently use any Rust 2018 features.

Breaking Changes

Breaking changes are minimized. When they are made they will be outlined below with transition guidelines.

Thrift 0.12.0
  • [THRIFT-4529] - Rust enum variants are now camel-cased instead of uppercased to conform to Rust naming conventions

    Previously, enum variants were uppercased in the auto-generated code. For example, the following thrift enum:

    // THRIFT
    enum Operation {
      ADD,
      SUBTRACT,
      MULTIPLY,
      DIVIDE,
    }
    

    used to generate:

    // OLD AUTO-GENERATED RUST
    pub enum Operation {
       ADD,
       SUBTRACT,
       MULTIPLY,
       DIVIDE,
     }
    

    It now generates:

    // NEW AUTO-GENERATED RUST
    pub enum Operation {
       Add,
       Subtract,
       Multiply,
       Divide,
     }
    

    You will have to change all enum variants in your code to use camel-cased names. This should be a search and replace.

Contributing

Bug reports and PRs are always welcome! Please see the Thrift website for more details.

Thrift Rust support requires code in several directories:

  • compiler/cpp/src/thrift/generate/t_rs_generator.cc: binding code generator
  • lib/rs: runtime library
  • lib/rs/test: supplemental tests
  • tutorial/rs: tutorial client and server
  • test/rs: cross-language test client and server

All library code, test code and auto-generated code compiles and passes clippy without warnings. All new code must do the same! When making changes ensure that:

  • rustc does does output any warnings
  • clippy with default settings does not output any warnings (includes auto-generated code)
  • cargo test is successful
  • make precross and make check are successful
  • tutorial/bin/tutorial_client and tutorial/bin/tutorial_server communicate
