Module parse

Expand description

Tree-sitter parsing and source-span collection.

Structs§

collect_spans: Parses C# source and returns its namespace, type, and member declaration spans.
is_ts_js: Whether rel is a TS/JS file – ts_grammar_for(rel).is_some().
node_text: Text of node out of a utf16_bytes buffer – the UTF-16 counterpart of Node::utf8_text, and the only way to read source text in this crate.
parse_ts_js: One parse of source under grammar. Parser::parse returns None only on cancellation/malformed-input-size edge cases, never on ordinary syntax errors (those surface as ERROR nodes inside a still-present tree).
run_parse: Parses the C# file at path and prints its syntax tree.
run_spans: Collects declaration spans from the C# file at path and prints them as JSON.
spans_json: Serializes span records as a JSON array.
ts_grammar_for: Maps a file extension to its grammar. Based on the last . in rel, not path-aware: a dotted directory segment on a file with no extension of its own would misfire (a known, accepted edge case).
utf16_bytes: The same units as a little-endian byte buffer, which is what node byte offsets index into and therefore what every text() helper slices.
utf16_index: UTF-16 code-unit index for a byte offset (or column) reported by a tree parsed out of a utf16_bytes buffer.
utf16_units: Encodes source text as UTF-16 code units.
