Trait Handler 

pub trait Handler: Send + Sync {
    // Required method
    fn call(
        &self,
        args: &str,
    ) -> Pin<Box<dyn Future<Output = Result<String, String>> + Send + '_>>;
}

Handler trait for protocol-agnostic request handling

Handlers implement this trait to provide a unified interface that can be called from any protocol adapter.

Required Methods

fn call( &self, args: &str, ) -> Pin<Box<dyn Future<Output = Result<String, String>> + Send + '_>>

Call the handler with JSON args and return a result
