Enum CentroidStore

Source

pub enum CentroidStore {
    Owned(Array2<f32>),
}

Expand description

Storage backend for centroids, supporting both owned arrays and memory-mapped files.

This enum enables ResidualCodec to work with centroids stored either:

In memory as an owned Array2<f32> (default, for Index and LoadedIndex)
Memory-mapped from disk (for MmapIndex, reducing RAM usage)

Variants§

§

Owned(Array2<f32>)

Centroids stored as an owned ndarray (loaded into RAM)

Implementations§

Source §

impl CentroidStore

Source

pub fn view(&self) -> ArrayView2<'_, f32>

Get a view of the centroids as ArrayView2.

This is zero-copy for both owned and mmap variants.

Source

pub fn nrows(&self) -> usize

Get the number of centroids (rows).

Source

pub fn ncols(&self) -> usize

Get the embedding dimension (columns).

Source

pub fn row(&self, idx: usize) -> ArrayView1<'_, f32>

Get a view of a single centroid row.

Source

pub fn slice_rows(&self, start: usize, end: usize) -> ArrayView2<'_, f32>

Get a view of rows [start..end] as ArrayView2.

This is zero-copy for both owned and mmap variants.
