> Display which binary will be run for a command managed by `rustup`.

> More information: <https://rust-lang.github.io/rustup>.

- Display the path to the binary in the default toolchain:

`rustup which {{command}}`

- Display the path to the binary in the specified toolchain (see `rustup help toolchain` for more information):
