cargo-mextk is both an executable binary that can be run, and a library that can be used in Rust programs.
Installing the command-line executable
Assuming you have Rust/Cargo installed, run this command in a terminal:
cargo install cargo-mextk
It will make the cargo-mextk command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall cargo-mextk uninstalls.
Adding cargo_mextk library as a dependency
Run this command in a terminal, in your project's directory:
cargo add cargo-mextk
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
cargo-mextk = "0.3.1"
The cargo_mextk library will be automatically available globally.
Read the cargo_mextk library documentation.
