impl<Fut, E> Debug for ErrInto<Fut, E> where
    MapErr<Fut, IntoFn<E>>: Debug, 

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Fut, E> FusedFuture for ErrInto<Fut, E> where
    MapErr<Fut, IntoFn<E>>: FusedFuture, 

pub fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.

impl<Fut, E> Future for ErrInto<Fut, E> where
    MapErr<Fut, IntoFn<E>>: Future, 

type Output = <MapErr<Fut, IntoFn<E>> as Future>::Output

The type of value produced on completion.

pub fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>
