Upstream Tooling

rules_rust manages versions of things like rustc. If you want to manually run upstream tooling configured at the versions, plugins and such that rules_rust has configured, rules_rust exposes these as targets in @rules_rust//tools/upstream_wrapper:

% bazel query @rules_rust//tools/upstream_wrapper
@rules_rust//tools/upstream_wrapper:cargo
@rules_rust//tools/upstream_wrapper:cargo_clippy
@rules_rust//tools/upstream_wrapper:rustc
@rules_rust//tools/upstream_wrapper:rustfmt

You can run them via bazel run, e.g. bazel run @rules_rust//tools/upstream_wrapper:cargo -- check.
