Allows storing providers for different types in a unified collection. The concrete type is recovered via Any::downcast_ref() at runtime.

Required Methods

fn topic_any(&self, value: &dyn Any) -> Option<String>

Get the topic for a type-erased value

Returns None if the value type doesn’t match or if the provider returns None for this value.

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