Struct IndexSnapshot

pub struct IndexSnapshot;

Expand description

Snapshot I/O for an HnswIndex.

All multi-byte integers are stored as little-endian u64 / u32. Floating-point values are stored as little-endian f32.

Implementations§

impl IndexSnapshot

pub fn save<W: Write>( index: &HnswIndex, writer: &mut W, ) -> Result<usize, VectorError>

Serialize index into writer.

Returns the total number of bytes written.

pub fn load<R: Read>(reader: &mut R) -> Result<HnswIndex, VectorError>

Deserialize an HnswIndex from reader.

pub fn save_to_file( index: &HnswIndex, path: &Path, ) -> Result<usize, VectorError>

Persist index to a file at path.

The file is created (or truncated) atomically via a temporary sibling file.

pub fn load_from_file(path: &Path) -> Result<HnswIndex, VectorError>

Load an index from a file at path.
