Expand description
Represents a single subscription that is waiting to be accepted or rejected.
If this is dropped without calling PendingSubscription::reject
or PendingSubscriptionSink::accept
a default error is sent out as response to the subscription call.
Thus, if you want a customized error message then PendingSubscription::reject
must be called.
Fields§
§inner: MethodSink
Sink.
method: &'static str
MethodCallback
.
subscribers: Arc<Mutex<HashMap<(ConnectionId, Id<'static>), (MethodSink, Receiver<()>, u64)>>>
Shared Mutex of subscriptions for this method.
id: Id<'static>
ID of the subscription call
(i.e. not the same as subscription id) which is used
to reply to subscription method call and must only be used once.
subscribe: Sender<MethodResponse>
Sender to answer the subscribe call.
channel_id: u64
Channel identifier.
connection_id: ConnectionId
Connection identifier.
Implementations§
source§impl PendingSubscriptionSink
impl PendingSubscriptionSink
sourcepub async fn accept(self) -> Result<SubscriptionSink, String>
pub async fn accept(self) -> Result<SubscriptionSink, String>
Attempt to accept the subscription and respond the subscription method call.
§Panics
Panics if the subscription response exceeded the max_response_size
.
sourcepub fn channel_id(&self) -> u64
pub fn channel_id(&self) -> u64
Returns the channel identifier
