Trait UListener

Source

pub trait UListener: Send + Sync {
    // Required method
    fn on_receive<'life0, 'async_trait>(
        &'life0 self,
        msg: UMessage,
    ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Expand description

A handler for processing uProtocol messages.

Implementations contain the details for what should occur when a message is received.

Please refer to the uProtocol Transport Layer specification for details.

Required Methods§

Source

fn on_receive<'life0, 'async_trait>( &'life0 self, msg: UMessage, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Performs some action on receipt of a message.

§Parameters

msg - The message to process.

§Implementation hints

This function is expected to return almost immediately. If it does not, it could potentially block processing of succeeding messages. Long-running operations for processing a message should therefore be run on a separate thread.
