This crate provides rst language support for the tree-sitter parsing library.
Typically, you will use the language function to add this language to a tree-sitter Parser, and then use the parser to parse some code:
let code = "";
let mut parser = tree_sitter::Parser::new();
parser.set_language(tree_sitter_rst::language()).expect("Error loading rst grammar");
let tree = parser.parse(code, None).unwrap();
