Trait samotop_core::service::mail::MailQueue

pub trait MailQueue: Send + Sync {
    type Mail: Sink<Bytes, Error = Error>;
    type MailFuture: Future<Output = Option<Self::Mail>>;
    fn mail(&self, envelope: Envelope) -> Self::MailFuture;
}

A mail queue allows us to queue an e-mail. For a given mail envelope it produces a Sink that can receive mail data. Once the sink is closed successfully, the mail is queued.
