Detailed Description

template<typename EventType, std::size_t InlineSize = 32>
class corium::internal::EventHandlerDelegate< EventType, InlineSize >

Lightweight non-allocating delegate wrapper with 32-byte Small Buffer Optimization (SBO). Eliminates std::function heap allocations and virtual table overhead for event handlers.

Template Parameters

EventType

The concrete event type invoked by this delegate.
