1//! This crate provides TS corpus test language support for the [tree-sitter] parsing library.
2//!
3//! Typically, you will use the [`LANGUAGE`] constant 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//! ==================
9//! Return statements
10//! ==================
11//!
12//! func x() int {
13//!   return 1;
14//! }
15//!

22//!     (primitive_type)
23//!     (block
24//!       (return_statement (number)))))
25//! "#;
26//! let mut parser = tree_sitter::Parser::new();
27//! let language = tree_sitter_test::LANGUAGE;
28//! parser
29//!     .set_language(&language.into())
30//!     .expect("Error loading TS corpus test parser");
31//! let tree = parser.parse(code, None).unwrap();
32//! assert!(!tree.root_node().has_error());
33//! ```
