Struct MqttOptions

pub struct MqttOptions { /* private fields */ }

Options to configure the behaviour of mqtt connection

Implementations

impl MqttOptions

pub fn new<S: Into<String>, T: Into<String>>( id: S, host: T, port: u16, ) -> MqttOptions

New mqtt options

pub fn broker_address(&self) -> (String, u16)

Broker address

pub fn set_last_will(&mut self, will: LastWill) -> &mut Self

pub fn last_will(&mut self) -> Option<LastWill>

pub fn set_ca(&mut self, ca: Vec<u8>) -> &mut Self

pub fn ca(&self) -> Option<Vec<u8>>

pub fn set_client_auth(&mut self, cert: Vec<u8>, key: Vec<u8>) -> &mut Self

pub fn client_auth(&self) -> Option<(Vec<u8>, Vec<u8>)>

pub fn set_alpn(&mut self, alpn: Vec<Vec<u8>>) -> &mut Self

pub fn alpn(&self) -> Option<Vec<Vec<u8>>>

pub fn set_keep_alive(&mut self, secs: u16) -> &mut Self

Set number of seconds after which client should ping the broker if there is no other data exchange

pub fn keep_alive(&self) -> Duration

Keep alive time

pub fn client_id(&self) -> String

Client identifier

pub fn set_max_packet_size(&mut self, sz: usize) -> &mut Self

Set packet size limit (in Kilo Bytes)

pub fn max_packet_size(&self) -> usize

Maximum packet size

pub fn set_clean_session(&mut self, clean_session: bool) -> &mut Self

clean_session = true removes all the state from queues & instructs the broker to clean all the client state when client disconnects.

When set false, broker will hold the client state and performs pending operations on the client when reconnection with same client_id happens. Local queue state is also held to retransmit packets after reconnection.

pub fn clean_session(&self) -> bool

Clean session

pub fn set_credentials<S: Into<String>>( &mut self, username: S, password: S, ) -> &mut Self

Username and password

pub fn credentials(&self) -> Option<(String, String)>

Security options

pub fn set_notification_channel_capacity( &mut self, capacity: usize, ) -> &mut Self

Set notification channel capacity

pub fn notification_channel_capacity(&self) -> usize

Notification channel capacity

pub fn set_request_channel_capacity(&mut self, capacity: usize) -> &mut Self

Set request channel capacity

pub fn request_channel_capacity(&self) -> usize

Request channel capacity

pub fn set_throttle(&mut self, duration: Duration) -> &mut Self

Enables throttling and sets outoing message rate to the specified ‘rate’

pub fn throttle(&self) -> Duration

Outgoing message rate

pub fn set_inflight(&mut self, inflight: usize) -> &mut Self

Set number of concurrent in flight messages

pub fn inflight(&self) -> usize

Number of concurrent in flight messages
