Struct Subscription 

Source 
pub struct Subscription<'a, T: Read + Write, C: Clock, P: Protocol, const L: usize>
where
    HelloCommand: Command<<P as Protocol>::FrameType>,
    <P as Protocol>::FrameType: From<CommandBuilder> + ToPushMessage,
{ /* private fields */ }
Expand description

Client for handling subscriptions

L: Number of subscribed topics

Implementations§

Source§

impl<'a, T, C, P, const L: usize> Subscription<'a, T, C, P, L>
where T: Read + Write, C: Clock, P: Protocol, HelloCommand: Command<<P as Protocol>::FrameType>, <P as Protocol>::FrameType: From<CommandBuilder> + ToPushMessage,

Source

pub fn new(client: Client<'a, T, C, P>, topics: [Bytes; L]) -> Self

Source

pub async fn receive(&mut self) -> Result<Option<Message>, Error>

Waits for and receives the next published message.

Source

pub async fn unsubscribe(self) -> Result<(), Error>

Unsubscribes from all topics and waits for confirmation

If this fails, the owned connection is dropped to avoid reusing an undefined state.
