Struct Inspect
#[must_use = "futures/streams/sinks do nothing unless you `.await` or poll them"]
pub struct Inspect<St, F> { /* private fields */ }
Stream for the inspect method.
Implementations
impl<St, F> Inspect<St, F>
fn get_ref(&self) -> &StAcquires a reference to the underlying sink or stream that this combinator is pulling from.
fn get_mut(&mut self) -> &mut StAcquires 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) -> StConsumes 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.
