Expand description

Storage layout and quantization metadata, with explicit references to all data.

Variants§

§

Dense

Addressable scalar values with explicit shape and strides.

Fields

§tensor: StoredTensor

Physical view of the scalar values.

§

Affine

Grouped integer codes reconstructed using scales and an affine offset.

Fields

§bits: u8

Bits per quantized value.

§group_size: u64

Logical values sharing one scale and offset.

§group_axis: usize

Axis along which quantization groups are formed.

§packing: BitPacking

Order of codes within each storage word.

§codes: StoredTensor

Packed integer codes.

§scales: StoredTensor

One scale per quantization group.

§offset: AffineOffset

Additive biases or integer zero points, one per group.

§

Ggml

GGML blocks whose layout is determined by the encoding code.

Fields

§encoding: GgmlEncoding
§

Opaque

Uninterpreted storage retained for a future adapter.

Fields

§name: String
§metadata: Value

Implementations§

Source§

impl TensorEncoding

Source

pub fn data(&self) -> Vec<&DataSpan>

Explicit references remain enumerable even for an unknown encoding.

Source§

impl TensorEncoding

Source

pub fn validate(&self) -> Result<()>

Check component layouts and supported affine grouping constraints. For GGML and opaque data, only span arithmetic is checked.
