Struct TopicProviderWrapper 

pub struct TopicProviderWrapper<T, P>
where
    T: 'static,
    P: TopicProvider<T>,
{ /* private fields */ }

Wrapper struct for type-erasing a TopicProvider<T>

This wraps a concrete TopicProvider<T> implementation and provides the TopicProviderAny interface for type-erased storage.

Uses PhantomData<fn(T) -> T> instead of PhantomData<T> to avoid inheriting Send/Sync bounds from T (the data type isn’t stored).
