This crate provides Diff language support for the tree-sitter parsing library.

Typically, you will use the [LANGUAGE][] constant to add this language to a tree-sitter Parser, and then use the parser to parse some code:

let code = r#"
diff --git a/tree-sitter-gitdiff.wasm b/tree-sitter-gitdiff.wasm
index 0e9e828..3e32290 100755
Binary files a/tree-sitter-gitdiff.wasm and b/tree-sitter-gitdiff.wasm differ

"#;
let mut parser = tree_sitter::Parser::new();
let language = tree_sitter_diff::LANGUAGE;
parser
    .set_language(&language.into())
    .expect("Error loading Diff parser");
let tree = parser.parse(code, None).unwrap();
assert!(!tree.root_node().has_error());
