Not disagreeing that cargo-raze in bazel is awkward, but just wanted to add:

Cargo raze should let you consume libraries you've imported in a rust_binary target, if that's what you're talking about. It's also possible, but slightly more annoying, to vendor the dependency tree if you need to rely on pulling from a local mirror.

I've also used it to import cargo binaries (i.e wasm-bindgen-cli) into a Bazel workspace -- it just makes the resulting target something like @raze_some_bin//:bin
