Trait MessageHandler 

pub trait MessageHandler<T: Send + Sync + 'static>:
    Send
    + Sync
    + 'static {
    // Required method
    fn handle<'life0, 'async_trait>(
        &'life0 self,
        msg: Message<T>,
    ) -> Pin<Box<dyn Future<Output = AppResult<()>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Handler for processing consumed messages.

Implement this trait to define how incoming messages are processed. For simple cases, use FnHandler to wrap a closure.

Required Methods

fn handle<'life0, 'async_trait>( &'life0 self, msg: Message<T>, ) -> Pin<Box<dyn Future<Output = AppResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Process a single message.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
