//! This crate provides Typescript and TSX grammars for the [tree-sitter][] parsing library.
//!
//! Typically, you will use the [language_typescript][language func] function to add this grammar to a
//! tree-sitter [Parser][], and then use the parser to parse some code:
//!
//! ```
//! use tree_sitter::Parser;
//!
//! let code = r#"
//!     function double(x: number): number {
//!         return x * 2;
//!     }
//! "#;
//! let mut parser = Parser::new();
//! parser
//!     .set_language(tree_sitter_typescript::language_typescript())
//!     .expect("Error loading typescript grammar");
//! let parsed = parser.parse(code, None).unwrap();
//! let root = parsed.root_node();
//! assert!(!root.has_error());
//! ```
