This folder integrates Rust crates.io fetching into Bazel.
To update dependencies, ensure a local Rust environment is available
(eg source scripts/cargo-env), then install cargo-raze:
cargo install cargo-raze --version 0.13.0
cargo install cargo-license
After updating dependencies in ../rslib/Cargo.toml, change to this folder and run python update.py to update the external Bazel repositories to point to the updated deps.
Note: cargo-raze does not currently work when run from Windows, and nobody has investigated why yet. For now, you'll need a Mac or Linux machine, or will need to run update.py from within WSL.
A couple of crates need extra work to build with Bazel, and are listed in ../Cargo.toml. For example:
[package.metadata.raze.crates.pyo3.'*']
compile_data_attr = "glob([\"**\"])"
With minor version updates, you should not normally need to modify the entries in that file.
Because update.py modifies a lot of files in remote/, it makes it difficult to review in a PR, and the changes can sometimes break platforms like Windows. For this reason, please don't submit PRs that do minor version bumps - those will typically be done after stable releases. If you need a new crate for a feature you're working on, please raise it in an issue first.
Reqwest
Things are complicated with reqwest at the moment, because:
- we're using a fork to implement better timeouts for syncing
- we want to build it with different features on Linux (where we can't build a wheel that links to OpenSSL), and on other platforms.
For minor version bumps, update.py should take care of updating the versions of reqwest dependencies.
After making a big update to reqwest via an updated fork, the vendored BUILD.reqwest.* files may need updating. To do that, comment native-tls from the features in rslib/Cargo.toml and run update.py, and copy the file in remote/ over the old vendored file. Then comment the other two deps out, add native-tls back, and repeat the process.
