Trait Implementations

impl Clone for VRFOutput

fn clone(&self) -> VRFOutput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VRFOutput

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

Formats the value using the given formatter.

impl Decode for VRFOutput

fn decode<R: Input>(i: &mut R) -> Result<Self, Error>

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 Deref for VRFOutput

type Target = VRFOutput

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for VRFOutput

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Encode for VRFOutput

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

Convert self to an owned vector.

fn size_hint(&self) -> usize

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

fn encode_to<T>(&self, dest: &mut T)where T: Output + ?Sized,

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

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl MaxEncodedLen for VRFOutput

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq<VRFOutput> for VRFOutput

fn eq(&self, other: &VRFOutput) -> 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.

fn try_from(raw: [u8; 32]) -> Result<Self, Self::Error>

Performs the conversion.

impl TypeInfo for VRFOutput

type Identity = [u8; 32]

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
