Expand description
The receiving end of a queue trigger channel
Implementations§
source§impl TriggerReceiver
impl TriggerReceiver
sourcepub async fn listen(&mut self) -> Result<(), QueueTriggerClosedError>
pub async fn listen(&mut self) -> Result<(), QueueTriggerClosedError>
Listen for one or more items to come through, draining the channel each time. Bubble up errors on empty channel.

The inverse inclusion map: attempts to construct
self
from the equivalent element of its
superset. Read more§fn is_in_subset(&self) -> bool

(and can be converted to it).§fn to_subset_unchecked(&self) -> SS
fn to_subset_unchecked(&self) -> SS
Use with care! Same as
self.to_subset
