Trait tsukuyomi_session::Backend

pub trait Backend {
    type Session: RawSession;
    type ReadError: Into<Error>;
    type ReadSession: TryFuture<Ok = Self::Session, Error = Self::ReadError>;

    fn read(&self) -> Self::ReadSession;
}

A trait representing the session backend.

Required Associated Types

type Session: RawSession

The type of session which will be crated by ReadSession.

type ReadError: Into<Error>

The type or errors which will occur when polling ReadSession.

type ReadSession: TryFuture<Ok = Self::Session, Error = Self::ReadError>

The type of TryFuture that will return a Session.

Required Methods

fn read(&self) -> Self::ReadSession

Creates a TryFuture to create a Session asynchronously.
