Struct CublasScope 

pub struct CublasScope {
    pub ffn: bool,
    pub attn: bool,
    pub ssm: bool,
    pub head: bool,
}

2026-09-25: Which projection families take a cuBLASLt GEMM arm, so one family can be armed without the others.

Grammar: METRALE_CUBLAS_GEMM=<token>[,<token>]*, ASCII-case-insensitive, whitespace around a token ignored:

token	meaning
ffn	dense-FFN and MoE shared-expert projections
attn	attention Q/K/V, O and the output gate
ssm	GDN in_proj_qkvz and out_proj
head	LM / MTP head (see CublasScope::head)
all, 1, true	every family
off, 0, false, empty	the empty set

The result is the union of the tokens, so off clears nothing (ffn,off is ffn). Unknown tokens are dropped and reported, and never widen the set.

Fields

ffn: bool

2026-09-25: Dense-FFN gate/up/down and the MoE shared expert.

attn: bool

2026-09-25: Attention Q/K/V, O projection and the output gate.

ssm: bool

2026-09-25: GDN in_proj_qkvz and out_proj, in prefill and decode.

head: bool

2026-09-25: LM / MTP head. Parsed and set by all, but no dispatch site reads it, so setting it changes nothing.

Implementations

impl CublasScope

pub const OFF: Self

2026-09-25: No family armed: what an absent, empty or off METRALE_CUBLAS_GEMM resolves to, and the value in GemmDispatch::defaults.

pub const ALL: Self

2026-09-25: Every family: what all, 1 and true resolve to.

pub fn any(&self) -> bool

2026-09-25: Whether any family is armed.

Trait Implementations

impl Clone for CublasScope

fn clone(&self) -> CublasScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CublasScope

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

Formats the value using the given formatter.

impl Default for CublasScope

fn default() -> CublasScope

Returns the “default value” for a type.

impl PartialEq for CublasScope

fn eq(&self, other: &CublasScope) -> 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.
