Implementations

impl VrfPreOutput

pub fn make_bytes<const N: usize>( &self, context: &[u8], input: &VrfTranscript, public: &CryptoBytes<sp_core::::sr25519::Public::{constant#0}, Sr25519PublicTag>, ) -> Result<[u8; N], Error>

where [u8; N]: Default,

Generate output bytes from the given VRF configuration.

Trait Implementations

impl Clone for VrfPreOutput

fn clone(&self) -> VrfPreOutput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VrfPreOutput

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

Formats the value using the given formatter.

impl Decode for VrfPreOutput

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

where R: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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 Encode for VrfPreOutput

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) -> R

where 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 VrfPreOutput

fn max_encoded_len() -> usize

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

impl PartialEq for VrfPreOutput

fn eq(&self, other: &VrfPreOutput) -> 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 TypeInfo for VrfPreOutput

type Identity = [u8; 32]

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
