impl Hash for Const

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl InferenceRulesOp for Const

fn rules<'r, 'p: 'r, 's: 'r>( &'s self, s: &mut Solver<'r>, inputs: &'p [TensorProxy], outputs: &'p [TensorProxy], ) -> InferenceResult

Registers the inference rules of the operator.

fn as_op(&self) -> &dyn Op

fn to_typed( &self, _source: &InferenceModel, node: &InferenceNode, target: &mut TypedModel, mapping: &HashMap<OutletId, OutletId>, ) -> TractResult<TVec<OutletId>>

fn nboutputs(&self) -> TractResult<usize>

fn incorporate( &self, model: &InferenceModel, node: &InferenceNode, ) -> TractResult<Option<InferenceModelPatch>>

impl Op for Const
