whereis that crate?
When working in large Rust codebases, one occasionally encounters repositories containing dozens
or hundreds of individual crates. Rust knows where they all are, due to the definitions in
Cargo.toml, but it's not always so obvious to the developer. This tool makes it easy to locate the
actual path of a crate.
Produce the path to a crate in the workspace:
substrate$ cargo whereis --relative sp-offchain primitives/offchain
Produce the URL of a dependency:
substrate$ cargo whereis --url lazy_static https://crates.io/crates/lazy_static
Produce either a local filesystem path or a URL if you're not sure:
substrate$ cargo whereis --force parity-scale-codec https://crates.io/crates/parity-scale-codec
