Sourcefn push_pending_play_promise(&self, promise: &Rc<Promise>)
fn push_pending_play_promise(&self, promise: &Rc<Promise>)
Appends a promise to the list of pending play promises.
Sourcefn take_pending_play_promises(&self, result: ErrorResult)
fn take_pending_play_promises(&self, result: ErrorResult)
Takes the pending play promises.
The result with which these promises will be fulfilled is passed here
and this method returns nothing because we actually just move the
current list of pending play promises to the
in_flight_play_promises_queue field.
Each call to this method must be followed by a call to
fulfill_in_flight_play_promises, to actually fulfill the promises
which were taken and moved to the in-flight queue.
Sourcefn fulfill_in_flight_play_promises<F>(&self, f: F)where
F: FnOnce(),
fn fulfill_in_flight_play_promises<F>(&self, f: F)where
F: FnOnce(),
Fulfills the next in-flight play promises queue after running a closure.
See the comment on take_pending_play_promises for why this method
does not take a list of promises to fulfill. Callers cannot just pop
the front list off of in_flight_play_promises_queue and later fulfill
the promises because that would mean putting
#[cfg_attr(crown, allow(crown::unrooted_must_root))] on even more functions, potentially
hiding actual safety bugs.
