Struct SegmentBuilder 

pub struct SegmentBuilder { /* private fields */ }

Segment builder with optimized memory usage

Features:

• Streams documents to disk immediately (no in-memory document storage)
• Uses string interning for terms (reduced allocations)
• Uses hashbrown HashMap (faster than BTreeMap)
• Spills large posting lists to disk (bounded memory)
