Struct sp_core::bandersnatch::Signature

pub struct Signature(_);

Bandersnatch signature.

The signature is created via the VrfSecret::vrf_sign using SIGNING_CTX as label.

Trait Implementations

impl AsMut<[u8]> for Signature

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for Signature

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl ByteArray for Signature

const LEN: usize = 65usize

The “length” of the values of this type, which is always the same.

fn from_slice(data: &[u8]) -> Result<Self, ()>

A new instance from the given slice that should be Self::LEN bytes long.

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

Return a Vec<u8> filled with raw data.

fn as_slice(&self) -> &[u8]

Return a slice filled with raw data.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CryptoType for Signature

type Pair = Pair

The pair key type of this crypto.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Decode for Signature

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

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 Signature

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

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

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

Convert self to an owned vector.

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

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

fn size_hint(&self) -> usize

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Hash for Signature

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 MaxEncodedLen for Signature

fn max_encoded_len() -> usize

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

impl PartialEq<Signature> for Signature

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

impl PassBy for Signature

type PassBy = Inner<Signature, [u8; 65]>

The strategy that should be used to pass the type.

impl PassByInner for Signature

type Inner = [u8; 65]

The inner type that is wrapped by Self.

fn into_inner(self) -> Self::Inner

Consumes self and returns the inner type.

fn inner(&self) -> &Self::Inner

Returns the reference to the inner type.

fn from_inner(inner: Self::Inner) -> Self

Construct Self from the given inner.

impl TryFrom<&[u8]> for Signature

type Error = ()

The type returned in the event of a conversion error.

fn try_from(data: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TypeInfo for Signature

type Identity = Signature

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl UncheckedFrom<[u8; 65]> for Signature

fn unchecked_from(raw: [u8; 65]) -> Self

Convert from an instance of T to Self. This is not guaranteed to be whatever counts as a valid instance of T and it’s up to the caller to ensure that it makes sense.
