tree_sitter_ygg/
lib.rs

1//! This crate provides a Rust grammar for the [tree-sitter][] parsing library.
2//!
3//! Typically, you will use the [language][language func] function to add this grammar to a
4//! tree-sitter [Parser][], and then use the parser to parse some code:
5//!
6//! ```
7//! use tree_sitter::Parser;
8//!
9//! let code = r#"
10//!     fn double(x: i32) -> i32 {
11//!         x * 2
12//!     }
13//! "#;
14//! let mut parser = Parser::new();
15//! parser.set_language(tree_sitter_ygg::language()).expect("Error loading Rust grammar");
16//! let parsed = parser.parse(code, None);
17//! # let parsed = parsed.unwrap();
18//! # let root = parsed.root_node();
19//! # assert!(!root.has_error());
20//! ```
