Trait Handler 

pub trait Handler<T: ?Sized>: 'static {
    // Required methods
    fn id(&self) -> Ustr;
    fn handle(&self, message: &T);
}

Compile-time type-safe message handler trait.

Provides zero-cost dispatch for statically typed messages. Can also be used with dyn Any for dynamic dispatch when type flexibility is needed.

Required Methods

fn id(&self) -> Ustr

Returns the unique identifier for this handler.

fn handle(&self, message: &T)

Handles a message of type T.

Dyn Compatibility

This trait is dyn compatible.

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