Struct PublishBuilder

pub struct PublishBuilder { /* private fields */ }

Implementations

impl PublishBuilder

pub fn packet_id(self, id: u16) -> Self

Set packet id.

Note: if packet id is not set, it gets generated automatically. Packet id management should not be mixed, it should be auto-generated or set by user. Otherwise collisions could occure.

panics if id is 0

pub fn dup(self, val: bool) -> Self

This might be re-delivery of an earlier attempt to send the Packet.

pub fn retain(self, val: bool) -> Self

Set retain flag

pub fn properties<F>(self, f: F) -> Self

where F: FnOnce(&mut PublishProperties),

Set publish packet properties

pub fn set_properties<F>(&mut self, f: F)

where F: FnOnce(&mut PublishProperties),

Set publish packet properties

pub fn size(&self) -> u32

Get size of the publish packet

pub fn send_at_most_once(self) -> Result<(), SendPacketError>

Send publish packet with QoS 0

pub fn send_at_least_once( self, ) -> impl Future<Output = Result<PublishAck, SendPacketError>>

Send publish packet with QoS 1

pub fn send_at_least_once_no_block(self) -> Result<(), SendPacketError>

Non-blocking send publish packet with QoS 1

Panics if sink is not ready or publish ack callback is not set
