Detailed Description

template<typename FunctionSignature>
class helios::Delegate< FunctionSignature >

Type-erased callable wrapper for free and member functions.

Delegate is a lightweight, non-owning wrapper for:

• Free functions
• Member functions (including const and virtual)

It does not allocate and stores only:

• A raw instance pointer (for member functions, may be null for free functions)
• A function pointer to a small thunk that performs the actual call

The delegate is intentionally minimal and exception-free. It returns default-constructed values when empty (for non-void return types) and is a no-op for void return types.

Template Parameters

FunctionSignature

Function type in the form R(Args...).
