treesitter-types-cpp 0.1.1

Pre-generated strongly-typed AST types for C++ (tree-sitter-cpp)
Documentation

Strongly-typed AST types for C++, auto-generated from tree-sitter-cpp's node-types.json.

This crate is generated by treesitter-types and is automatically kept up to date when a new version of the grammar crate is released.

These types have been tested by parsing the nlohmann/json source code.

See the Tree-sitter project for more information about the underlying parser framework.

Example

use treesitter_types_cpp::*;

// A minimal C++ hello-world program.
let src = b"\
#include <iostream>

int main() {
    std::cout << \"Hello, World!\" << std::endl;
    return 0;
}
";

// Parse the source with tree-sitter and convert into typed AST.
let mut parser = tree_sitter::Parser::new();
parser.set_language(&tree_sitter_cpp::LANGUAGE.into()).unwrap();
let tree = parser.parse(src, None).unwrap();
let tu = TranslationUnit::from_node(tree.root_node(), src).unwrap();

// The translation unit has two top-level children.
assert_eq!(tu.children.len(), 2);

// 1) The #include directive.
let TranslationUnitChildren::PreprocInclude(include) = &tu.children[0] else {
    panic!("expected a preproc include");
};
assert_eq!(include.span.start.row, 0);

// 2) The `main` function definition.
let TranslationUnitChildren::FunctionDefinition(func) = &tu.children[1] else {
    panic!("expected a function definition");
};
assert!(func.body.is_some()); // has a function body
