Fields

mode: Option<CompressionMode>

Compression mode.

anchor_frequency: Option<u32>

Frequency (in insertions) at which anchor vectors are written.

quantization_bits: Option<u32>

Bit-width used during quantisation.

Implementations

impl CompressionConfig

pub fn new(mode: CompressionMode) -> Self
