fn dyn_hash(&self, state: &mut dyn Hasher)

impl EvalOp for GatherElements

fn is_stateless(&self) -> bool

fn eval(&self, inputs: TVec<Arc<Tensor>>) -> TractResult<TVec<Arc<Tensor>>>

fn same_as(&self, _other: &dyn Op) -> bool

Compare two ops.

fn info(&self) -> TractResult<Vec<String>>

Short (one-line) strings giving hints on internal implementation or important configuration details to be displayed in dumps.

impl TypedOp for GatherElements

fn as_op(&self) -> &dyn Op

Reinterpret the TypedOp as an Op.

fn as_op_mut(&mut self) -> &mut dyn Op

Reinterpret the TypedOp as an Op, mutably.

fn output_facts(&self, inputs: &[&TypedFact]) -> TractResult<TVec<TypedFact>>

fn fuse(
    &self,
    _model: &TypedModel,
    _node: &TypedNode

Fuse op after codegen to deal with local optimisations.

fn declutter(
    &self,
    model: &TypedModel,
    node: &TypedNode
