Enum DsaShard 

pub enum DsaShard {
    Replicated,
    HeadRows,
    HeadCols,
}

2026-09-25: How one DSA tensor maps onto TP ranks.

Variants

Replicated

2026-09-25: Every rank holds the whole tensor: the indexer, the latent KV projection, and the low-rank down-projections and norms.

HeadRows

2026-09-25: Leading dim is heads * per_head: slice by this rank’s head range.

HeadCols

2026-09-25: Trailing (input) dim is heads * v_head_dim: a row-parallel GEMM, sliced on the input dim, whose output is all-reduced.

Trait Implementations

impl Clone for DsaShard

fn clone(&self) -> DsaShard

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DsaShard

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DsaShard

fn eq(&self, other: &DsaShard) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
