Implementations

impl<T, E, I, C> BatchReceiver<T, E, I, C> where
    T: Unpin,
    E: Unpin,
    I: Fn() -> E + Unpin,
    C: BatchCollector<E, T> + Unpin
[src]

pub fn new(
    rx: Receiver<T>,
    max_batch_size: usize,
    initializer: I,
    collector: C
) -> Self
[src]

Creates a new BatchReceiver with given initializer and collector. initializer is used to generate a initial value, and collector will collect every (at most max_batch_size) raw items into the batched value.
