Rust Rules

Overview

This repository provides rules for building Rust projects with Bazel.

Basics

Protobuf

with an overview here.

Setup

To use the Rust rules, add the following to your WORKSPACE file to add the external repositories for the Rust toolchain:

http_archive(
    name = "io_bazel_rules_rust",
    sha256 = "c82118824b2448b77146f1dae97b6eaa717babedad0822aca4879f3cbbf2b7b5",
    strip_prefix = "rules_rust-3228ccd3814c2ad0d7307d2f87fb8ff9616149d7",
    urls = [
        # Master branch as of 2018-12-11
        "https://github.com/bazelbuild/rules_rust/archive/3228ccd3814c2ad0d7307d2f87fb8ff9616149d7.tar.gz",
    ],
)

http_archive(
    name = "bazel_skylib",
    sha256 = "eb5c57e4c12e68c0c20bc774bfbc60a568e800d025557bc4ea022c6479acc867",
    strip_prefix = "bazel-skylib-0.6.0",
    url = "https://github.com/bazelbuild/bazel-skylib/archive/0.6.0.tar.gz",
)

load("@io_bazel_rules_rust//rust:repositories.bzl", "rust_repositories")
rust_repositories()

load("@io_bazel_rules_rust//:workspace.bzl", "bazel_version")
bazel_version(name = "bazel_version")

The rules are under active development, as such the lastest commit on the master branch should be used. master currently requires Bazel >= 0.17.0.

External Dependencies

Currently the most common approach to managing external dependencies is using cargo-raze to generate BUILD files for Cargo crates.

Roadmap

Improve expressiveness of features and support for Cargo's feature groups.
Add cargo_crate workspace rule for pulling crates from Cargo.
