//! This crate provides Jrpc language support for the [tree-sitter][] parsing library.

|

|
|
//! Typically, you will use the [language][language func] function to add this language to a

||
|
|
//! tree-sitter [Parser][], and then use the parser to parse some code:
|

|
|
//!
|
||
|
|
//! ```
|
||
|
|
//! let code = r#"
|

//! let mut parser = tree_sitter::Parser::new();

//! let language = tree_sitter_jrpc::LANGUAGE;

//! parser

//! .set_language(&language.into())

//! .expect("Error loading Jrpc parser");

//! let tree = parser.parse(code, None).unwrap();
|
