Struct futures_bounded::FuturesMap

source ·
pub struct FuturesMap<ID, O> { /* private fields */ }
Expand description

Represents a map of Futures.

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

Implementations§

source§

impl<ID, O> FuturesMap<ID, O>

source

pub fn new(timeout: Duration, capacity: usize) -> Self

source§

impl<ID, O> FuturesMap<ID, O>
where ID: Clone + Hash + Eq + Send + Unpin + 'static, O: 'static,

source

pub fn try_push<F>( &mut self, future_id: ID, future: F ) -> Result<(), PushError<BoxFuture<'_, O>>>
where F: Future<Output = O> + Send + 'static,

Push a future into the map.

This method inserts the given future with defined future_id to the set. If the length of the map is equal to the capacity, this method returns PushError::BeyondCapacity, that contains the passed future. In that case, the future is not inserted to the map. If a future with the given future_id already exists, then the old future will be replaced by a new one. In that case, the returned error PushError::Replaced contains the old future.
