Rust
//! This crate provides Solidity language support for the [tree-sitter][] parsing library.
|
|
//!
|
|
//! The bindings in https://github.com/tree-sitter/tree-sitter-javascript/blob/master/bindings/rust were used
|
|
//! as a template for the tree-sitter-solidity rust bindings.
|
|
//!
|
|
//! 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 = "";
|
|
//! let mut parser = tree_sitter::Parser::new();
|
|
//! parser.set_language(tree_sitter_solidity::language()).expect("Error loading Solidity grammar");
|
|
//! let tree = parser.parse(code, None).unwrap();
|
|
//! ```
|
|
//!

//! [Language]: https://docs.rs/tree-sitter/*/tree_sitter/struct.Language.html

//! [language func]: fn.language.html
