Any

using Acts::Any = AnyBase<sizeof(void*), true>

A type-safe container for single values of any type.

This is a custom implementation similar to std::any but optimized for small types that can fit into a pointer-sized buffer. Values larger than a pointer are stored on the heap.

AnyMoveOnly

using Acts::AnyMoveOnly = AnyBase<sizeof(void*), false>

Move-only variant that can store move-only types (e.g.

std::unique_ptr)

Same as Any but copy constructor and copy assignment are deleted. Use when storing types that are not copyable.
