Trait completion_io::AsyncSeekWith

pub trait AsyncSeekWith<'a> {
    type SeekFuture: CompletionFuture<Output = Result<u64>>;
    fn seek(&'a mut self, pos: SeekFrom) -> Self::SeekFuture;
}

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

Associated Types

type SeekFuture: CompletionFuture<Output = Result<u64>>

Future that seeks to an offset a stream. If successful, resolves to the new position from the start of the stream.
