Struct SearchIndex 

pub struct SearchIndex { /* private fields */ }

RAM-resident trigram index over one project root.

Implementations

impl SearchIndex

pub fn build( root: &str, respect_gitignore: bool, allow_secret_paths: bool, ) -> Option<Self>

Build the index by walking root with the exact same config and filters as ctx_search, so the searchable file universe is identical.

pub fn candidate_paths(&self, pattern: &str, ext: Option<&str>) -> CandidateSet

Candidate files for pattern, filtered by ext. None means “no safe narrowing possible” — the caller should scan the full file list.

Narrowing is applied only for pure [A-Za-z0-9_] literals of length ≥ 3. For such a literal every match contains it on a single line, hence the file contains all of its consecutive trigrams: intersecting their posting lists yields a superset of matching files (zero false negatives), which the caller then regex-verifies.
