Struct StreamMap 

pub struct StreamMap<ID, O> { /* private fields */ }

Represents a map of Streams.

Each stream must finish within the specified time and the map never outgrows its capacity.

Implementations

impl<ID, O> StreamMap<ID, O>

where ID: Clone + Unpin,

pub fn new( make_delay: impl Fn() -> Delay + Send + Sync + 'static, capacity: usize, ) -> Self

impl<ID, O> StreamMap<ID, O>

where ID: Clone + PartialEq + Send + Unpin + 'static, O: Send + 'static,

pub fn try_push<F>( &mut self, id: ID, stream: F, ) -> Result<(), PushError<Pin<Box<dyn AnyStream<Item = O> + Send>>>>

where F: AnyStream<Item = O>,

Push a stream into the map.

pub fn remove( &mut self, id: ID, ) -> Option<Pin<Box<dyn AnyStream<Item = O> + Send>>>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn poll_ready_unpin(&mut self, cx: &mut Context<'_>) -> Poll<()>

pub fn poll_next_unpin( &mut self, cx: &mut Context<'_>, ) -> Poll<(ID, Option<Result<O, Timeout>>)>

pub fn iter_of_type<T>(&self) -> impl Iterator<Item = (&ID, Pin<&T>)>

where T: 'static,

Returns an iterator over all streams of type T pushed via StreamMap::try_push. This iterator returns streams in an arbitrary order, which may change.

If downcasting a stream to T fails it will be skipped in the iterator.

pub fn iter_mut_of_type<T>( &mut self, ) -> impl Iterator<Item = (&ID, Pin<&mut T>)>

where T: 'static,

Returns an iterator with mutable access over all streams of type T pushed via StreamMap::try_push. This iterator returns streams in an arbitrary order, which may change.

If downcasting a stream to T fails it will be skipped in the iterator.
