matts1 / bazel-rust-analyzer

A wrapper to allow rust-analyzer to work with bazel-based projects.

bazel-rust-analyzer README

Features

• Automatically generate rust-project.json and configures automatic linting with bazel.

Requirements

Currently requires using a custom rules_rust. Hopefully will soon be able to be pushed into upstream rules_rust.

Add the following to your bazelrc:

build --@rules_rust//:output_diagnostics=true --output_groups=+rust_lib_rustc_output,+rust_metadata_rustc_output

Extension Settings

• bazel-rust-analyzer.genRustProjectCommand: Custom command to generate a rust project
• bazel-rust-analyzer.autoGenRustProjectCommand: Whether to automatically generate a rust project when a new .rs file is opened (default: false).

Usage

• Control shift P > "Generate a rust-project.json for all open files" to tell rust-analyzer to configure a watcher to pay attention to all .rs files currently open in bazel.
• When a bazel target including any rust files that were open at the time you invoked the previous command is built:
  • If the build fails, the errors should be analyzed and highlighted in the editor.
  • If the build succeeds, rust-analyzer should be able to analyze your target for file types and analyze your dependencies.
