Struct gj::PromiseFulfiller

pub struct PromiseFulfiller<T, E> where
    T: 'static,
    E: 'static + FulfillerDropped,  { /* fields omitted */ }

A handle that can be used to fulfill or reject a promise. If you think of a promise as the receiving end of a oneshot channel, then this is the sending end.

When a PromiseFulfiller<T,E> is dropped without first receiving a fulfill(), reject(), or resolve() call, its promise is rejected with the error value E::fulfiller_dropped().
