#[must_use = "sinks do nothing unless polled"]
pub struct WithFlatMap<Si, U, St, F> where
    Si: Sink,
    F: FnMut(U) -> St,
    St: Stream<Item = Result<Si::SinkItem, Si::SinkError>>, 
{ /* fields omitted */ }

Sink for the Sink::with_flat_map combinator, chaining a computation that returns an iterator to run prior to pushing a value into the underlying sink.

Methods

impl<Si, U, St, F> WithFlatMap<Si, U, St, F> where
    Si: Sink,
    F: FnMut(U) -> St,
    St: Stream<Item = Result<Si::SinkItem, Si::SinkError>>, 
[src]

Important traits for &'a mut W

Get a shared reference to the inner sink.

Important traits for &'a mut W

Get a mutable reference to the inner sink.

Get a pinned mutable reference to the inner sink.

Consumes this combinator, returning the underlying sink.

Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
