ⓘImportant traits for &'_ mut Fpub fn get_ref(&self) -> &Si[src]
ⓘImportant traits for &'_ mut F
Get a shared reference to the inner sink.
ⓘImportant traits for &'_ mut Fpub fn get_mut(&mut self) -> &mut Si[src]
ⓘImportant traits for &'_ mut F
Get a mutable reference to the inner sink.
ⓘImportant traits for Pin<P>pub fn get_pin_mut(

) -> Pin<&mut Si>[src]
ⓘImportant traits for Pin<P>
self: Pin<&mut WithFlatMap<Si, Item, U, St, F>>
) -> Pin<&mut Si>
Get a pinned mutable reference to the inner sink.
pub fn into_inner(self) -> Si[src]
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.
