Function parse_with_tree_sitter 

pub fn parse_with_tree_sitter(
    source: &str,
    language: &Language,
    extract_symbols: impl FnOnce(Node<'_>, &str, &mut Vec<ExtractedSymbol>, &mut Vec<ExtractedImport>),
    extract_calls: impl FnOnce(Node<'_>, &str, &[ExtractedSymbol]) -> Vec<ExtractedCall>,
    extract_type_refs: impl FnOnce(Node<'_>, &str, &[ExtractedSymbol]) -> Vec<ExtractedTypeRef>,
) -> ParseResult

Parse source code with a tree-sitter language and language-specific extractors.

The parse-tree construction and ParseResult assembly is identical for every language; only the extraction callbacks differ.
