fn seek(&mut self, pos: SeekFrom) -> Seek<Self>

Important traits for Seek<'_, S>

impl<'_, S> Future for Seek<'_, S> where
    S: Unpin + AsyncSeek + ?Sized
type Output = Result<u64, Error>;

Creates a future which will seek an IO object, and then yield the new position in the object and the object itself.

In the case of an error the buffer and the object will be discarded, with the error yielded.
