Fix bzl loads (#262) Migrating rules_rust for these incompatible changes: bazelbuild/bazel#9006 bazelbuild/bazel#8922 bazelbuild/bazel#8743
This repository provides rules for building Rust projects with Bazel.
To build a rust_binary
for wasm32-unknown-unknown add the --platforms=//rust/platform:wasm
flag.
bazel build @examples//hello_world_wasm --platforms=//rust/platform:wasm
rust_wasm_bindgen
will automatically transition to the wasm platform and can be used when building wasm code for the host target.
with an overview here.
To use the Rust rules, add the following to your WORKSPACE
file to add the external repositories for the Rust toolchain:
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive") http_archive( name = "io_bazel_rules_rust", sha256 = "b6da34e057a31b8a85e343c732de4af92a762f804fc36b0baa6c001423a70ebc", strip_prefix = "rules_rust-55f77017a7f5b08e525ebeab6e11d8896a4499d2", urls = [ # Master branch as of 2019-10-07 "https://github.com/bazelbuild/rules_rust/archive/55f77017a7f5b08e525ebeab6e11d8896a4499d2.tar.gz", ], ) http_archive( name = "bazel_skylib", sha256 = "9a737999532daca978a158f94e77e9af6a6a169709c0cee274f0a4c3359519bd", strip_prefix = "bazel-skylib-1.0.0", url = "https://github.com/bazelbuild/bazel-skylib/archive/1.0.0.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 >= 0.26.0.
Currently the most common approach to managing external dependencies is using cargo-raze to generate BUILD
files for Cargo crates.
cargo_crate
workspace rule for pulling crates from Cargo.
