//! This crate provides Query language support for the [tree-sitter][] parsing library.
//!
//! Typically, you will use the [LANGUAGE][] constant to add this language to a
//! tree-sitter [Parser][], and then use the parser to parse some code:
//!
//! ```
//! let code = r#"
//! (program
//! (named_node
//! name: (identifier)))
//! "#;
//! let mut parser = tree_sitter::Parser::new();
//! let language = tree_sitter_query::LANGUAGE;
//! parser
//! .set_language(&language.into())
//! .expect("Error loading Query parser");
//! let tree = parser.parse(code, None).unwrap();
//! assert!(!tree.root_node().has_error());
//! ```
//!
//! [Parser]: https://docs.rs/tree-sitter/*/tree_sitter/struct.Parser.html
//! [tree-sitter]: https://tree-sitter.github.io/
