Struct ClientShutdownHandle 

pub struct ClientShutdownHandle { /* private fields */ }

An owned handle that can be used to disconnect and shutdown an MQTT client’s transceiver task and obtain its ShutdownStatus.

Should this value be dropped without calling ClientShutdownHandle::disconnect() beforehand, the client’s transceiver task will be detached.

Implementations

impl ClientShutdownHandle

pub async fn disconnect(self) -> Result<ShutdownStatus, JoinError>

Enqueues a disconnect command, causing the transceiver task to attempt to disconnect gracefully and shutdown. Unlike Client::disconnect(), this function will wait for the transceiver task to complete before returning, and also returns a ShutdownStatus, which can be used to know whether the client managed to disconnect gracefully or not.
