Type Alias 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.

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
