Struct Extractor

Source

pub struct Extractor { /* private fields */ }

Expand description

Reusable trigram extractor. Pre-allocated, reused across files.

Implementations§

Source §

impl Extractor

Source

pub fn new() -> Self

Create a new extractor with pre-allocated capacity.

Source

pub fn extract_with_offsets(&mut self, data: &[u8]) -> &[(Trigram, u32)]

Extract trigrams with byte offsets (for indexing).

Returns a slice of (trigram, offset) pairs, sorted by trigram then offset.

Source

pub fn extract_set(query: &[u8]) -> Vec<Trigram> ⓘ

Extract unique trigram set from a query (no offsets needed).

Source

pub fn extract_groups_case_insensitive(query: &[u8]) -> Vec<Vec<Trigram>>

Extract trigram groups with case permutations for case-insensitive search.

Returns one group per original trigram position. Each group contains all case variants for that position (max 8 per group for 3 ASCII alpha bytes). The executor should UNION within each group and INTERSECT across groups.
