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<(), Error>

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: SmallVec<[TValue; 4]> ) -> Result<SmallVec<[TValue; 4]>, Error>

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

impl FrozenOpState for Slice

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

impl Hash for Slice

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 Op for Slice

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

fn info(&self) -> Result<Vec<String, Global>, Error>

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 + 'static)>

fn same_as(&self, other: &(dyn Op + 'static)) -> 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 + 'static), inputs: SmallVec<[TValue; 4]> ) -> Result<SmallVec<[TValue; 4]>, Error>

impl OpStateFreeze for Slice

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

impl PartialEq<Slice> 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] ) -> Result<SmallVec<[TypedFact; 4]>, Error>

Deduce output facts from input facts.

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

fn declutter( &self, model: &Graph<TypedFact, Box<dyn TypedOp, Global>>, node: &Node<TypedFact, Box<dyn TypedOp, Global>> ) -> Result<Option<ModelPatch<TypedFact, Box<dyn TypedOp, Global>>>, Error>

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

fn concretize_dims( &self, _source: &Graph<TypedFact, Box<dyn TypedOp, Global>>, node: &Node<TypedFact, Box<dyn TypedOp, Global>>, target: &mut Graph<TypedFact, Box<dyn TypedOp, Global>>, mapping: &HashMap<OutletId, OutletId, RandomState>, values: &SymbolValues ) -> Result<SmallVec<[OutletId; 4]>, Error>

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

fn as_op(&self) -> &(dyn Op + 'static)

Reinterpret the TypedOp as an Op.

fn as_op_mut(&mut self) -> &mut (dyn Op + 'static)

Reinterpret the TypedOp as an Op, mutably.

fn fuse( &self, _model: &Graph<TypedFact, Box<dyn TypedOp, Global>>, _node: &Node<TypedFact, Box<dyn TypedOp, Global>> ) -> Result<Option<ModelPatch<TypedFact, Box<dyn TypedOp, Global>>>, Error>

Fuse op after codegen to deal with local optimisations.

fn declutter_with_session( &self, session: &mut OptimizerSession<'_>, model: &Graph<TypedFact, Box<dyn TypedOp, Global>>, node: &Node<TypedFact, Box<dyn TypedOp, Global>> ) -> Result<Option<ModelPatch<TypedFact, Box<dyn TypedOp, Global>>>, Error>

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

fn cost( &self, _inputs: &[&TypedFact] ) -> Result<SmallVec<[(Cost, TDim); 4]>, Error>

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

fn codegen( &self, model: &Graph<TypedFact, Box<dyn TypedOp, Global>>, node: &Node<TypedFact, Box<dyn TypedOp, Global>> ) -> Result<Option<ModelPatch<TypedFact, Box<dyn TypedOp, Global>>>, Error>

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

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