Trait Implementations

impl Clone for Slice

fn clone(&self) -> Slice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Slice

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

Formats the value using the given formatter.

impl Default for Slice

fn default() -> Slice

Returns the “default value” for a type.

impl EvalOp for Slice

fn is_stateless(&self) -> bool

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

fn state( &self, _session: &mut SessionState, _node_id: usize ) -> TractResult<Option<Box<dyn OpState>>>

impl FrozenOpState for Slice

fn unfreeze(&self) -> Box<dyn OpState>

impl Hash for Slice

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

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 Op for Slice

fn name(&self) -> Cow<'_, str>

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

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

fn as_typed(&self) -> Option<&dyn TypedOp>

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

Compare two ops.

fn validation(&self) -> Validation

The kind of accuracy check that should be performed on operation when testing them.

impl OpState for Slice

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

impl OpStateFreeze for Slice

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

impl PartialEq for Slice

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TypedOp for Slice

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

Deduce output facts from input facts.

fn axes_mapping( &self, inputs: &[&TypedFact], outputs: &[&TypedFact] ) -> TractResult<AxesMapping>

fn change_axes( &self, model: &TypedModel, node: &TypedNode, _io: InOut, change: &AxisOp ) -> TractResult<Option<AxisChangeConsequence>>

fn declutter( &self, model: &TypedModel, node: &TypedNode ) -> TractResult<Option<TypedModelPatch>>

Declutter the op to the tract_core operator set as much as possible.

fn concretize_dims( &self, _source: &TypedModel, node: &TypedNode, target: &mut TypedModel, mapping: &HashMap<OutletId, OutletId>, values: &SymbolValues ) -> TractResult<TVec<OutletId>>

Transform the op into by providing a value to one or more symbols.

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 fuse( &self, _model: &TypedModel, _node: &TypedNode ) -> TractResult<Option<TypedModelPatch>>

Fuse op after codegen to deal with local optimisations.

fn declutter_with_session( &self, session: &mut OptimizerSession<'_>, model: &TypedModel, node: &TypedNode ) -> TractResult<Option<TypedModelPatch>>

Declutter the op to the tract_core operator set as much as possible.

fn cost(&self, _inputs: &[&TypedFact]) -> TractResult<TVec<(Cost, TDim)>>

Computes a cost hint of the operation.

fn suggested_axis_changes(&self) -> TractResult<TVec<(InOut, AxisOp)>>

fn slice( &self, patch: &mut TypedModelPatch, prefix: &str, inputs: &[OutletId], output_axis: usize, start: usize, end: usize ) -> TractResult<Option<TVec<OutletId>>>

fn quantize( &self, model: &TypedModel, node: &TypedNode, dt: DatumType, scale: f32, zero_point: i32 ) -> TractResult<Option<Box<dyn TypedOp>>>

Transforms the op in an equivalent one, operating on dt (i8 or u8).

fn codegen( &self, model: &TypedModel, node: &TypedNode ) -> TractResult<Option<TypedModelPatch>>

Translate the op into the most efficient form possible for execution.

fn nested_model_multipliers( &self, inputs: &[&TypedFact] ) -> Vec<(Cow<'_, str>, f64)>

Nested model multipliers, with label (for profiling).
