Type Alias polkadot_core_primitives::Signature

pub type Signature = MultiSignature;

Alias to type for a signature for a transaction on the relay chain. This allows one of several kinds of underlying crypto to be used, so isn’t a fixed size when encoded.

Aliased Type

enum Signature {
    Ed25519(CryptoBytes<64, (SignatureTag, Ed25519Tag)>),
    Sr25519(CryptoBytes<64, (SignatureTag, Sr25519Tag)>),
    Ecdsa(CryptoBytes<65, (SignatureTag, EcdsaTag)>),
}

Variants

Ed25519(CryptoBytes<64, (SignatureTag, Ed25519Tag)>)

An Ed25519 signature.

Sr25519(CryptoBytes<64, (SignatureTag, Sr25519Tag)>)

An Sr25519 signature.

Ecdsa(CryptoBytes<65, (SignatureTag, EcdsaTag)>)

An ECDSA/SECP256k1 signature.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<'de> Deserialize<'de> for MultiSignature

fn deserialize<__D>( __deserializer: __D, ) -> Result<MultiSignature, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for MultiSignature

fn size_hint(&self) -> usize

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

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

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>(&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 From<CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>> for MultiSignature

fn from( x: CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>, ) -> MultiSignature

Converts to this type from the input type.

impl From<CryptoBytes<sp_core::::ed25519::Signature::{constant#0}, (SignatureTag, Ed25519Tag)>> for MultiSignature

fn from( x: CryptoBytes<sp_core::::ed25519::Signature::{constant#0}, (SignatureTag, Ed25519Tag)>, ) -> MultiSignature

Converts to this type from the input type.

impl From<CryptoBytes<sp_core::::sr25519::Signature::{constant#0}, (SignatureTag, Sr25519Tag)>> for MultiSignature

impl MaxEncodedLen for MultiSignature

fn max_encoded_len() -> usize

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

impl PartialEq for MultiSignature

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Verify for MultiSignature

type Signer = MultiSigner

Type of the signer.

fn verify<L>(&self, msg: L, signer: &AccountId32) -> bool

where L: Lazy<[u8]>,

Verify a signature.
