Enum ScannEncoding 

pub enum ScannEncoding {
    AsymmetricHash {
        dimensions_per_block: u16,
        bits_per_code: u8,
    },
    BinaryHamming,
}

Leaf representation used by the segment-local ScaNN payload.

Variants

AsymmetricHash

Residual asymmetric-hash codes for floating-point embeddings.

Fields

dimensions_per_block: u16

bits_per_code: u8

BinaryHamming

Exact packed binary embeddings scored with Hamming distance.

Implementations

impl ScannEncoding

pub fn row_code_bytes(self, dimension: u32) -> ScannResult<usize>

pub fn leaf_code_bytes(self, dimension: u32, rows: usize) -> ScannResult<usize>

Encoded byte length for one leaf’s corpus-sized code column. AH uses the imported 32-lane FastScan layout for complete blocks and compact row-major packing for the tail.
