Trait sp_session::GetSessionNumber
source · [−]pub trait GetSessionNumber {
fn session(&self) -> SessionIndex;
}Expand description
A utility trait to get a session number. This is implemented for
MembershipProof below to fetch the session number the given session
membership proof is for. It is useful when we need to deal with key owner
proofs generically (i.e. just typing against the KeyOwnerProofSystem
trait) but still restrict their capabilities.
