Detailed Description
Type-safe optional value container.
Provides an alternative<TYPE> class that can either contain a value of type 'TYPE' or be in an empty state (represented by original::none from types.h). This implementation provides:
- Value semantics with proper construction/destruction
- Safe access operations with error checking
- In-place construction
- Move and copy operations
- Specialization for void type
- Integration with std::swap
Key features:
- Type-safe alternative to raw pointers for optional values
- No dynamic memory allocation (uses union storage)
- Explicit empty state handling with original::none
- Exception-safe operations
- STL-compatible interface
