Struct SynthesizedComputation

pub struct SynthesizedComputation { /* private fields */ }

A synthesized computation.

Implementations

impl SynthesizedComputation

pub fn new( expr: Expression, arg_interpretation: Vec<Arg>, consts: Vec<i128>, output_encoding: OutputEncoding, output_type: IoType, ) -> Self

Creates a new SynthesizedComputation.

pub fn always_false() -> Self

Returns a computation that always returns 0.

pub fn always_true() -> Self

Returns a computation that always returns 1.

pub fn output_type(&self) -> IoType

Returns the output type of the computation.

pub fn output_encoding(&self) -> OutputEncoding

Returns the output encoding of the computation.

pub fn set_output_encoding(&mut self, output_encoding: OutputEncoding)

Replaces the output encoding of the computation with output_encoding.

Trait Implementations

impl AsComputationRef for SynthesizedComputation

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.

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 Clone for SynthesizedComputation

fn clone(&self) -> SynthesizedComputation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Computation for SynthesizedComputation

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.

impl Debug for SynthesizedComputation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SynthesizedComputation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SynthesizedComputation

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 JsonSchema for SynthesizedComputation

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for SynthesizedComputation

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for SynthesizedComputation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
