Struct InMemorySegment 

pub struct InMemorySegment<'a> {
    pub id: SegmentId,
    pub scheme: u16,
    pub dims: u32,
    pub codes: Vec<u8>,
    pub factors: InMemorySegmentFactors,
    pub rescore: Vec<f32>,
    pub columns: &'a ColumnStore,
    pub alive: &'a AliveSet,
}

One complete already-built segment whose vector buffers can be adopted by a store.

Metadata and alive state remain caller-borrowed during the synchronous seal. The store takes ownership only of the three vector buffers whose exact capacities become part of resident_owned_bytes.

Fields

id: SegmentId

Sortable immutable identity.

scheme: u16

Permanent per-segment quantization scheme id.

dims: u32

Logical vector dimension.

codes: Vec<u8>

Contiguous row-major packed codes with no row padding.

factors: InMemorySegmentFactors

Contiguous factor records matching scheme.

rescore: Vec<f32>

Contiguous row-major f32 exact-rescore source.

columns: &'a ColumnStore

Typed metadata arrays aligned to row ids.

alive: &'a AliveSet

Alive/tombstone state aligned to row ids.
