tw2s 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 tw2s
It will make the tw2s command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall tw2s uninstalls.
Adding tw2s library as a dependency
Run this command in a terminal, in your project's directory:
cargo add tw2s
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
tw2s = "1.0.21"
The tw2s library will be automatically available globally.
Read the tw2s library documentation.
