pub trait AsyncSeekExt: AsyncSeek {
    pub fn seek(&mut self, pos: SeekFrom) -> Seek<'_, Self>ⓘNotable traits for Seek<'_, S>
impl<'_, S> Future for Seek<'_, S> where
    S: Unpin + AsyncSeek + ?Sized,     type Output = Result<u64, Error>;

    { ... }
}

An extension trait which adds utility methods to AsyncSeek types.

`pub fn seek(&mut self, pos: SeekFrom) -> Seek<'_, Self>ⓘNotable traits for Seek<'_, S> impl<'_, S> Future for Seek<'_, S> where S: Unpin + AsyncSeek + ?Sized, type Output = Result<u64, Error>; where Self: Unpin,` [src]

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.
