Trait IntoHandler 

pub trait IntoHandler<E: Event, Mode> { }

Type-erases a concrete handler into the internal representation expected by the bus registry.

This trait is implemented for:

• Structs implementing EventHandler<E> (selects AsyncMode).
• Structs implementing SyncEventHandler<E> (selects SyncMode).
• async fn(E) -> HandlerResult closures / function pointers (selects AsyncFnMode).
• fn(&E) -> HandlerResult closures / function pointers (selects SyncFnMode).

The Mode type parameter is inferred by the compiler from the concrete handler type; callers never need to name it explicitly.

You do not need to implement this trait manually — it is a blanket implementation over EventHandler and SyncEventHandler.
