Trait Implementations§

§

impl AsComputationRef for ComputationRef<'_, '_>

§

fn as_internal(&self) -> ComputationRef<'_, '_>

Return a ComputationRef.
§

fn to_synthesized_computation(&self) -> SynthesizedComputation

Return an owned SynthesizedComputation.
§

fn expr(&self) -> Expr<'_>

Return a reference to the expression used in the template.
§

fn arg_interpretation(&self) -> &[Arg]

Returns the argument interpretations of the computation.
§

fn if_zero<A: AsComputationRef, B: AsComputationRef>( &self, if_zero: &A, if_nonzero: &B, ) -> SynthesizedComputation

Returns a new expression that returns if_zero if the current expression is equal to 0, and returns if_nonzero otherwise.
§

fn chain(&self, other: &impl AsComputationRef) -> SynthesizedComputation
where Self: Debug,

Concatenates the operations of the two computations. In and of itself, this produces a computation that ends with two values on the evaluation stack. The last value is normally popped and returned, which would be the result of other. Read more
§

fn and(&self, other: &SynthesizedComputation) -> SynthesizedComputation
where Self: Debug,

Returns a computation that computes the bitwise AND of both computations.
§

fn or(&self, other: &SynthesizedComputation) -> SynthesizedComputation
where Self: Debug,

Returns a computation that computes the bitwise OR of both computations.
§

fn not(&self) -> SynthesizedComputation

Returns a computation that computes the bitwise NOT of the computation.
§

fn not_crop(&self) -> SynthesizedComputation

Returns a computation that computes the bitwise NOT of the computation, and then crops the result to 1 bit.
§

fn consts(&self) -> &[i128]

Returns the constants used in this computation.
§

impl<'template, 'a> Clone for ComputationRef<'template, 'a>

§

fn clone(&self) -> ComputationRef<'template, 'a>

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

§

impl Computation for ComputationRef<'_, '_>

§

fn evaluate<V: AsValue>(&self, inputs: &[V]) -> OwnedValue

Computes the output of the semantics, given inputs.
§

fn compare_eq<V: AsValue>(&self, inputs: &[V], expected: Value<'_>) -> bool

Returns true if expected matches the output of the computation. This function can be more efficient than manually comparing the result of self.evaluate(..). For example, we can avoid allocating a Vec for OwnedValue::Bytes results.
§

fn display<'a, S: AsRef<str>>( &'a self, input_names: &'a [S], ) -> impl Display + Debug + 'a

Returns a struct that is suitable for printing, which uses input_names in place of the inputs.
§

fn used_input_indices(&self) -> Vec<usize>

The indices of all inputs used in the computation.
§

fn remap_inputs(&mut self, _map: &[Option<usize>])

Remaps the input indices, such that new_index = map[old_index].unwrap_or(old_index).
§

fn is_identity(&self) -> bool

Returns true when the computation is the identity function. This function may under-approximate: it does not necessarily have to return true in all cases. Read more
§

impl<'template, 'a> Debug for ComputationRef<'template, 'a>

§

impl<'template, 'a> PartialEq for ComputationRef<'template, 'a>

§

fn eq(&self, other: &ComputationRef<'template, 'a>) -> bool

Tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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