Struct SegmentWriter 

pub struct SegmentWriter { /* private fields */ }

Accumulates documents and builds a segment on disk.

Symbols and refs stream straight into the columnar table builders as docs are added — the writer never materializes per-row structs, so peak memory during a build is the packed table bytes plus the postings pairs.

Implementations

impl SegmentWriter

pub fn new() -> Self

pub fn is_empty(&self) -> bool

pub fn doc_count(&self) -> usize

pub fn symbol_count(&self) -> usize

pub fn add_doc( &mut self, meta: DocMeta, trigram_keys: &[u32], symbols: Vec<RawSymbol>, refs: Vec<RawRef>, ) -> u32

Add a document and return its assigned doc id. trigram_keys must be the document’s distinct trigram keys (any order; typically sorted from trigram::extract_keys).

pub fn write(self, paths: &Paths, seg_id: u64) -> Result<()>

Serialize this segment to disk under the given segment id.

Trait Implementations

impl Default for SegmentWriter

fn default() -> Self

Returns the “default value” for a type.
