Struct zbus::MessageStream
source · pub struct MessageStream { /* private fields */ }
Expand description
A stream::Stream
implementation that yields Message
items.
You can convert a Connection
to this type and back to Connection
.
NOTE: You must ensure a MessageStream
is continuously polled or you will experience hangs.
If you don’t need to continuously poll the MessageStream
but need to keep it around for later
use, keep the connection around and convert it into a MessageStream
when needed. The
conversion is not an expensive operation so you don’t need to worry about performance, unless
you do it very frequently. If you need to convert back and forth frequently, you may want to
consider keeping both a connection and stream around.
