Fields

input_dim: usize

Input embedding dimension.

sketch_dim: usize

Output sketch dimension.

Larger values usually improve recall at the cost of more memory.

bits: u8

Number of bits per quantized coordinate.

Supported range: 1..=8.

hashes_per_input: u8

Number of non-zero sketch updates per input coordinate.

Larger values reduce projection noise but cost more CPU at encode time.

clip: f32

Symmetric clip range for the scaled sketch.

Coordinates are clipped to [-clip, clip] before scalar quantization.

seed: u64

Global seed used to derive sparse bucket locations and signs.

metric: SimilarityMetric

Similarity objective for scoring.

norm_log2_min: f32

Lower bound for log2(norm) when the norm channel is enabled.

norm_log2_max: f32

Upper bound for log2(norm) when the norm channel is enabled.
