Struct SegmentBuilder 

pub struct SegmentBuilder { /* private fields */ }

Builds a segment from analyzed documents.

Usage:

1. Create with new(segment_id, &schema)
2. Call add_document() for each document
3. Call build() to produce the segment bytes

Implementations

impl SegmentBuilder

pub fn new(segment_id: SegmentId, schema: &Mapping) -> Self

pub fn add_document( &mut self, analyzed_fields: &[(FieldId, Vec<Token>)], source: &[u8], )

Add a document with its analyzed fields and raw source JSON.

analyzed_fields contains (field_id, tokens) for each indexed field. Keyword fields should have a single token with the exact value. source is the original JSON bytes stored for _source retrieval.

pub fn mark_parent(&mut self)

Mark the most recently added doc as a parent (not nested).

pub fn mark_nested(&mut self)

Mark the current doc as a nested (hidden) doc.

pub fn add_geo_point(&mut self, field_id: FieldId, point: GeoPoint)

Add a geo point for a geo_point field.

pub fn add_geo_shape(&mut self, field_id: FieldId, geom: &Geometry<f64>)

Add a geo shape for a geo_shape field.

pub fn add_column_value(&mut self, field_id: FieldId, value: ColumnValue)

Add a column value for a doc_values field.

pub fn doc_count(&self) -> u32

Number of documents added so far.

pub fn segment_id(&self) -> SegmentId

The segment id assigned to this builder. Used by [IndexWriter::add] to stamp the current doc’s (segment_id, local_doc_id) pair into the global HNSW resolver before add_document is called.

pub fn is_empty(&self) -> bool

Is the buffer empty?

pub fn build(self) -> Vec<u8>

Build the complete segment bytes.

Returns the serialized segment including header, inverted index, norms, and document store.
