cargo-expand

This is a wrapper around cargo rustc -- --pretty=expanded. Once installed, the command cargo expand prints out the result of macro expansion applied to the current crate.

Installation

Install with cargo install cargo-expand.

This command optionally uses rustfmt to format the expanded output. If rustfmt is not available, the expanded code is not formatted. Install rustfmt with cargo install rustfmt.
