1//! This crate provides TOML 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 = r#"
8//! title = "TOML Example"
9//! "#;
10//! let mut parser = tree_sitter::Parser::new();
11//! let language = tree_sitter_toml::language();
12//! parser.set_language(&language).expect("Error loading TOML grammar");
13//! let tree = parser.parse(code, None).unwrap();
14//! assert!(!tree.root_node().has_error());
15//! ```
16//!
