Adding `lua_parser` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add lua_parser

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

lua_parser = "0.10.0"

The lua_parser library will be automatically available globally. Read the lua_parser library documentation.
