Trait MessageHandler 

pub trait MessageHandler: Send + Sync {
    // Required method
    fn handle<'life0, 'async_trait>(
        &'life0 self,
        message: ReceivedMessage<Value>,
    ) -> Pin<Box<dyn Future<Output = Result<MiddlewareResult, WorkerError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

A message handler that processes messages.

This trait represents a single step in the middleware chain. Handlers can be middleware components or final workers.

Required Methods

fn handle<'life0, 'async_trait>( &'life0 self, message: ReceivedMessage<Value>, ) -> Pin<Box<dyn Future<Output = Result<MiddlewareResult, WorkerError>> + Send + 'async_trait>>

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

Process a message.

Arguments

• message - The message to process

Returns

• Ok(MiddlewareResult::Acknowledged) if middleware handled acknowledgment
• Ok(MiddlewareResult::Continue) if processing should continue normally
• Err(WorkerError) if processing failed

Dyn Compatibility

This trait is dyn compatible.

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