How to do metadata-only typecheck build of a rust_library?

It looks like rules_rust unconditionally passes `--emit=dep-info,link`. This means Bazel builds cannot benefit from the biggest rustc speedup since 1.0.0 (https://blog.rust-lang.org/2017/03/16/Rust-1.16.html#whats-in-1160-stable). :crying_cat_face:

Is there any idiomatic way to perform non-code-generating builds which type-check only? Equivalent to Cargo's `cargo check` or `cargo rustc --profile=check`, rustc's `rustc --emit=metadata`, or Buck's #check flavored builds (`buck build :lib#check`; https://buck.build/concept/flavors.html#analysis_http).
