Struct W8a8Weight 

pub struct W8a8Weight { /* private fields */ }

2026-09-28: One W8A8 projection: up to three E4M3 weights with the same K and scale layout, stacked by rows into one output (attention Q|K|V, GDN QKV|Z, FFN gate|up). The checkpoint’s tensors are read in place.

Implementations

impl W8a8Weight

pub fn segment(&self, i: usize) -> Result<W8a8Weight>

2026-09-30: Segment i as a weight of its own. A segment’s output rows read only its own weight rows and scales, so its launch writes the bits the stacked launch writes for those rows.

pub fn segments(&self) -> usize

2026-09-30: Stacked segments.

impl W8a8Weight

pub fn new(segs: &[Fp8Weight]) -> Result<Self>

2026-09-28: Stack segs (1..=3). Errors unless they share K and a scale layout this family reads, K is a multiple of 128, and every segment but the last is a multiple of the layout’s segment alignment.

pub fn n(&self) -> u32

2026-09-28: Output rows (all segments).

pub fn k(&self) -> u32

2026-09-28: Contract width.

pub fn scale(&self) -> W8a8Scale
