source

type SignatureData

A signature data.

May contain account used for signing and the Signature itself.

Required Methods§

source

fn sign_message(&self, message: &[u8]) -> Self::SignatureData

Sign a message.

Implementation of this method should return a result containing the signature.

source

fn sign<TPayload, F>(&self, f: F) -> Self::SignatureDatawhere F: Fn(&Account<T>) -> TPayload, TPayload: SignedPayload<T>,

Construct and sign given payload.

This method expects f to return a SignedPayload object which is then used for signing.
