Rust toolchain

Chrome currently uses an experimental Rust toolchain built by the Android team, which supports only Linux and Android builds.

To build Rust code on other platforms for development/experimentation, add the following to your gn args:

use_unverified_rust_toolchain=true
rust_bin_dir="<path-to>/.cargo/bin"

Using VSCode, rust-analyzer etc.

Any IDE which supports rust-analyser should be able to ingest metadata from gn about the structure of our Rust project. Do this:

• gn gen out/Debug/ --export-rust-project
• ln -s out/Debug/rust-project.json rust-project.json, i.e. symlink the rust-project.json file to the root of the Chromium src directory.
