Cargo merge

A cargo subcommand that merges your crate source code into a single file.

The initial purpose of this command is to merge your whole crate as a single source file that can be used on competitive programming platforms.

It works by expanding module imports by detecting them with regex, rewriting some "use" statements in the process.

Install

Just run the following command:

cargo install cargo-merge

Usage

Simply call the cargo sub command inside your crate folder hierarchy (it can be any folder below the one containing your Cargo.toml file):

cargo merge

This will generate a merged file in target/merge/merged.rs.
