Struct GraphIndexer 

pub struct GraphIndexer { /* private fields */ }

Background indexer that walks a project directory, parses source files with tree-sitter, extracts symbols and call edges, and populates a shared CodeGraph.

Implementations

impl GraphIndexer

pub fn new(graph: Arc<RwLock<CodeGraph>>, project_dir: PathBuf) -> Self

Create a new indexer for the given project directory.

pub async fn index_all(&mut self, cancel: CancellationToken)

Full/incremental index pass.

1. Collect files via ignore::WalkBuilder (respects .gitignore)
2. Compare mtimes — only parse dirty/new files
3. Detect deleted files — remove from graph
4. Parse dirty files, extract symbols and calls
5. Resolve calls to edges

cancel is checked at every point where abandoning is cheap: top of the fn, between parse-file iterations (the expensive step), and before the final write-lock mutation block. Cancellation is cooperative — the sync WalkBuilder inside spawn_blocking cannot itself be interrupted, so best we can do is skip the parsing and mutation phases if cancel fires mid-walk. Rapid /cd chains depend on this: without it, each cd spawns a fresh indexer and all of them parse in parallel.

pub async fn reindex_file(&mut self, path: &Path)

Re-index a single file (for live updates after edit).
