[−] Expand description

An extension trait which adds utility methods to AsyncSeek types.

Provided methods

Important traits for Seek<'_, S>

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

fn seek(&mut self, pos: SeekFrom) -> Seek<Self> where
    Self: Unpin, [+]

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.
