Struct WeakBroadcastClient 

Source 
pub struct WeakBroadcastClient<'a, N: NetworkZone>(/* private fields */);
Expand description

A client used to send BroadcastMessages directly to a single peer, although these messages can be sent using a WeakClient or Client, using this client type allows bypassing the single request being handled at a time.

This means that if another WeakClient has a request in progress WeakBroadcastClient can still send messages and does not need to wait for the other WeakClient to finish.

A thing to note is that a call to WeakBroadcastClient::poll_ready will still reserve a slot in the queue, this should be kept in mind as many WeakBroadcastClients calling WeakBroadcastClient::poll_ready without WeakBroadcastClient::call will stop other WeakBroadcastClients & the other types of clients.

This type is kept in state with the WeakClient it was produced from, allowing you to do this:

ⓘ
weak_client.broadcast_client().poll_ready(cx)

weak_client.broadcast_client().call(req)
