to a tree-sitter <a href="https://docs.rs/tree-sitter/*/tree_sitter/struct.Parser.html"><code>Parser</code></a>, and then use the parser to parse some code:</p>

let x = 0

<p>Use <a href="constant.LANGUAGE_OCAML_INTERFACE.html"><code>LANGUAGE_OCAML_INTERFACE</code></a> to parse interface
files (with <code>.mli</code> extension) and <a href="constant.LANGUAGE_OCAML_TYPE.html"><code>LANGUAGE_OCAML_TYPE</code></a>
to parse type signatures.</p>
