Trait completion::io::AsyncSeekWith

pub trait AsyncSeekWith<'a> {
    type SeekFuture: CompletionFuture;
    pub fn seek(&'a mut self, pos: SeekFrom) -> Self::SeekFuture;
}

This is supported on crate feature std only.

A cursor which can be moved within a stream of bytes with a specific lifetime.
