Struct SegmentData 

pub struct SegmentData {
    pub docs: Vec<DocMeta>,
    /* private fields */
}

The immutable, shareable portion of an opened segment: mmaps, decoded side tables, and the derived lookup structures. Wrapped in an Arc so a daemon reloading its searcher after an incremental index can reuse unchanged segments instead of re-parsing and re-deriving everything.

Fields

Implementations

impl SegmentData

pub fn doc(&self, doc_id: u32) -> Option<&DocMeta>

pub fn doc_path_score(&self, doc_id: u32) -> f32

Path ranking adjustment for doc_id, or 0.0 if there is no such doc.

Computed on demand: [crate::search::path_score] allocates nothing, so precomputing a column of these at open cost more (one pass over every path in the repository, on the critical path of every cold query) than the per-hit calls it saved.

pub fn sym_count(&self) -> usize

Number of symbol rows in this segment (live or not).

pub fn sym(&self, i: u32) -> Option<SymbolEntry>

Decode symbol row i. None for out-of-range ids or a corrupt row.

pub fn doc_syms(&self, doc_id: u32) -> impl Iterator<Item = SymbolEntry> + '_

The symbols defined in doc_id, in storage order. O(1) range lookup.

pub fn doc_sym_count(&self, doc_id: u32) -> u32

Number of symbols defined in doc_id, without decoding any row.

pub fn doc_refs(&self, doc_id: u32) -> impl Iterator<Item = RefEntry> + '_

The references (calls + imports) originating in doc_id.

pub fn refs_named<'s>( &'s self, name: &'s str, ) -> impl Iterator<Item = RefEntry> + 's

References (calls and imports) whose name is exactly name, via the persisted name index (O(results), no full scan). Liveness is not filtered here; callers that care should check Segment::is_live.

pub fn calls_to<'s>( &'s self, name: &'s str, ) -> impl Iterator<Item = RefEntry> + 's

Call sites whose callee is exactly name (see Self::refs_named).

pub fn syms_by_lower<'s>( &'s self, lower: &'s str, ) -> impl Iterator<Item = u32> + 's

Symbol row ids whose lowercased name is exactly lower. O(results) via the persisted name FST.

pub fn sym_name(&self, i: u32) -> &str

Name of symbol row i (borrowed from the name column).

pub fn sym_name_lower(&self, i: u32) -> &str

Lowercased name of symbol row i (borrowed from the name column).
