   1 //! This crate provides api_notation language support for the [tree-sitter][] parsing library.
   2 //!
   3 //! Typically, you will use the [language][language func] function to add this language to a
   4 //! tree-sitter [Parser][], and then use the parser to parse some code:
   5 //!
   6 //! ```
   7 //! let code = "";
   8 //! let mut parser = tree_sitter::Parser::new();
   9 //! parser.set_language(tree_sitter_api_notation::language()).expect("Error loading api_notation grammar");
  10 //! let tree = parser.parse(code, None).unwrap();
  11 //! ```
  12 //!
