pub struct ConnectedUdpStream { /* private fields */ }
Expand description
Mimics TCP-like stream functionality on a UDP socket by restricting it to a single
counterparty and implements [tokio::io::AsyncRead
] and [tokio::io::AsyncWrite
].
The instance must always be constructed using a UdpStreamBuilder
.
To set a counterparty, one of the following must happen:
- setting it during build via
UdpStreamBuilder::with_counterparty
- receiving some data from the other side.
Whatever of the above happens first, sets the counterparty. Once the counterparty is set, all data sent and received will be sent or filtered by this counterparty address.
If data from another party is received, an error is raised, unless the object has been constructed
with ForeignDataMode::Discard
or ForeignDataMode::Accept
setting.
This object is also capable of parallel processing on a UDP socket.
If parallelism is set, the instance will create
multiple sockets with SO_REUSEADDR
and spin parallel tasks that will coordinate data and
transmission retrieval using these sockets. This is driven by RX/TX MPMC queues, which are
per-default unbounded (see queue size for details).
