Required Methods§

Source

fn sign(&mut self, message: Message) -> Result<Message, SignMessageError>

Source

fn sign_empty(&mut self) -> Option<Result<Message, SignMessageError>>

SigV4 requires an empty last signed message to be sent. Other protocols do not require one. Return Some(_) to send a signed last empty message, before completing the stream. Return None to not send one and terminate the stream immediately.
