Struct PackedQ2Weight 

pub struct PackedQ2Weight {
    pub weight: DevicePtr,
    pub n: u32,
    pub k: u32,
    pub group: u16,
}

2026-09-25: Keep-packed ternary Q2_0 weight: one buffer of raw block_q2_0 blocks ([fp16 d][group/4 bytes of 2-bit codes], value = (code - 1) * d), row-major over [n, k], with the scale inline and no separate scale tensor. Built from a WeightDtype::PackedQ2_0 store tensor, which the GGUF loader produces under METRALE_GGUF_NATIVE_Q2=1. The store owns the buffer; this struct only holds the pointer.

Fields

weight: DevicePtr

2026-09-25: Raw packed block_q2_0 bytes, n * (k/group) * (2 + group/4) long.

n: u32

2026-09-25: Output rows (the weight is [n, k]).

k: u32

2026-09-25: Input columns (the contraction dimension).

group: u16

2026-09-25: Elements per block and per inline scale.

Implementations

impl PackedQ2Weight
