cargo-path is a command-line utility that prints the path to a local Rust dependency.

It is invoked as cargo path <DEPENDENCY>. For example:

$ cargo path clap
/Users/home/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/clap-4.6.1

When combined with the appropriate exhortation, it is extremely helpful for Rust development with coding agents.

With cargo-path, agents will immediately consult local sources for dependencies, which are guaranteed to be up-to-date for the correct version.

Without cargo-path, agents tend to search the web for dependency documentation, which is slow and often turns up out-of-date information.

Always consult the local source code for information about Rust dependencies, which is guaranteed to be up-to-date for the correct version.

Run cargo path NAME to find the source directory for a dependency:

$ cargo path clap
/Users/home/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/clap-4.6.1
