Trait Implementations

impl<'a, 'b, F: FftField, D: EvaluationDomain<F>> Add<&'a Evaluations<F, D>> for &'b Evaluations<F, D>

type Output = Evaluations<F, D>

The resulting type after applying the + operator.

fn add(self, other: &'a Evaluations<F, D>) -> Evaluations<F, D>

Performs the + operation.

impl<'a, F: FftField, D: EvaluationDomain<F>> AddAssign<&'a Evaluations<F, D>> for Evaluations<F, D>

fn add_assign(&mut self, other: &'a Evaluations<F, D>)

Performs the += operation.

impl<F: FftField, D: EvaluationDomain<F>> CanonicalDeserialize for Evaluations<F, D>

fn deserialize<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads Self from reader.

fn deserialize_uncompressed<R: Read>(
    reader: R
) -> Result<Self, SerializationError>

Reads Self from reader without compression.

fn deserialize_unchecked<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads self from reader without compression, and without performing validity checks. Should be used only when the input is trusted.

impl<F: FftField, D: EvaluationDomain<F>> CanonicalSerialize for Evaluations<F, D>

fn serialize<W: Write>(&self, writer: W) -> Result<(), SerializationError>

Serializes self into writer. It is left up to a particular type for how it strikes the serialization efficiency vs compression tradeoff. For standard types (e.g. bool, lengths, etc.) typically an uncompressed form is used, whereas for algebraic types compressed forms are used.

fn serialized_size(&self) -> usize

fn serialize_uncompressed<W: Write>(
    &self,
    writer: W
) -> Result<(), SerializationError>

Serializes self into writer without compression.

fn serialize_unchecked<W: Write>(
    &self,
    writer: W
) -> Result<(), SerializationError>

Serializes self into writer without compression, and without performing validity checks. Should be used only when there is no danger of adversarial manipulation of the output.

fn uncompressed_size(&self) -> usize

impl<F: Clone + FftField, D: Clone + EvaluationDomain<F>> Clone for Evaluations<F, D>
