Wraps the Zircon vDSO API for Rust, using a misuse-resistant design (like std::fs::File) for kernel handles.
This crate is widely used which means that many targets can break due to changes and incremental builds cover many thousands of targets.
To iterate quickly, use fx clippy --all instead of fx build.
To ensure your changes don't break non-default targets, use a maximal build graph including buildbot targets. For example:
fx set core.x64 --debug \ --with-host //bundles/buildbot/host \ --with //bundles/buildbot/core \ --with //vendor/google/bundles/buildbot/core
Note: Presubmit might still fail on other architectures (arm64, riscv64) or specific tests. Check infra logs and builder config if that happens.
Depending on the breadth of your change's impact, it may be worthwhile to expand the list of buildbot bundles. Take a look at the subdirectories of //bundles/buildbot and //vendor/google/bundles/buildbot for options.
