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, EventBus) -> HandlerResult closures / function pointers (selects AsyncFnMode).
• fn(&E, &EventBus) -> 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
