Trait polkadot_node_subsystem::gen::futures::AsyncSeekExt

pub trait AsyncSeekExt: AsyncSeek {
    // Provided methods
    fn seek(&mut self, pos: SeekFrom) -> Seek<'_, Self> 
       where Self: Unpin { ... }
    fn stream_position(&mut self) -> Seek<'_, Self> 
       where Self: Unpin { ... }
}

An extension trait which adds utility methods to AsyncSeek types.

Provided Methods

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.

fn stream_position(&mut self) -> Seek<'_, Self> where Self: Unpin,

Creates a future which will return the current seek position from the start of the stream.

This is equivalent to self.seek(SeekFrom::Current(0)).
