pub fn get_or_parse_tree(
    file_path: &str,
    content: &str,
    parser: &mut Parser,
) -> Result<Tree>

Get a cached tree if available, otherwise parse and cache the result

Arguments

• file_path - The path of the file being parsed
• content - The content to parse
• parser - The tree-sitter parser to use if parsing is needed

Returns

A Result containing the parsed tree, either from cache or freshly parsed
