Struct TryFilterMap

#[must_use = "streams do nothing unless polled"]
pub struct TryFilterMap<St, Fut, F> { /* private fields */ }

Stream for the try_filter_map method.

Implementations

impl<St, Fut, F> TryFilterMap<St, Fut, F>

fn get_ref(&self) -> &St

Acquires a reference to the underlying sink or stream that this combinator is pulling from.

fn get_mut(&mut self) -> &mut St

Acquires a mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut St>

Acquires a pinned mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

fn into_inner(self) -> St

Consumes this combinator, returning the underlying sink or stream.

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