Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<P: Default + Pairing> Default for EvaluationKey<P>

where P::G1Affine: Default, P::G2Affine: Default, P::G2PairngRepr: Default,

fn default() -> EvaluationKey<P>

Returns the “default value” for a type.

impl<P: Pairing> Encode for EvaluationKey<P>

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.
