Struct OptMatMulState 

pub struct OptMatMulState { /* private fields */ }

Per-execution state for OptMatMul: on the trivial path it caches each micro-op’s Store OutputStore layout (strides fixed for the output shape), so only the base pointer is refreshed per call. Constant operands are baked into the op at fuse(), so they need no per-call state here. Pure memoization: dropped on freeze and rebuilt lazily on next eval.

Trait Implementations

impl Clone for OptMatMulState

fn clone(&self) -> OptMatMulState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptMatMulState

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

Formats the value using the given formatter.

impl Default for OptMatMulState

fn default() -> OptMatMulState

Returns the “default value” for a type.

impl OpState for OptMatMulState

fn eval( &mut self, session: &mut TurnState, op: &dyn Op, inputs: TVec<TValue>, ) -> TractResult<TVec<TValue>>

fn load_from( &mut self, _: &mut TurnState, _: &mut dyn Iterator<Item = TValue>, ) -> TractResult<()>

fn save_to(&self, _: &mut Vec<TValue>) -> TractResult<()>

fn init_tensor_fact(&self) -> Option<(String, TypedFact)>

fn has_init_tensor_fact(&self) -> bool

Allocation-free predicate mirroring whether OpState::init_tensor_fact returns Some. The per-run symbol-resolution path queries this once for every stateful op on every run, so it must not call init_tensor_fact (which clones a String and a TypedFact) merely to test for presence. Any impl that overrides init_tensor_fact to return Some must override this to return true (and delegate it wherever init_tensor_fact is delegated), or its resolve_symbols will not run.

fn resolve_symbols(&mut self, _: &mut TurnState) -> TractResult<()>

impl OpStateFreeze for OptMatMulState

fn freeze(&self) -> Box<dyn FrozenOpState>

fn freeze_into(self: Box<Self>) -> Box<dyn FrozenOpState>

Consuming freeze: moves data instead of cloning. Default delegates to freeze().
