Struct exonum::messages::Signed

pub struct Signed<T> { /* fields omitted */ }

Wraps a Payload together with the corresponding SignedMessage.

Usually one wants to work with fully parsed messages (i.e., Payload). However, occasionally we need to retransmit the message into the network or save its serialized form. We could serialize the Payload back, but Protobuf does not have a canonical form so the resulting payload may have different binary representation (thus invalidating the message signature).

So we use Signed to keep the original byte buffer around with the parsed Payload.
