pub struct DataWriter { /* private fields */ }
Expand description

The write half of a DataStream, implementing [futures::io::AsyncWrite].

See the DataStream docs for more information. In particular, note that this writer requires poll_flush to complete in order to guarantee that all data has been written.

Usage with Tokio

If the tokio crate feature is enabled, this type also implements tokio::io::AsyncWrite for easier integration with code that expects that trait.
