Type Safe
This library is a collection of zero-overhead C++ abstractions designed to replace primitive types with strict wrappers. By leveraging template metaprogramming, it enforces compile-time type safety and validates data integrity, ensuring that logic errors are caught during the build process rather than at runtime.
The project distinguishes itself by providing a zero-cost abstraction layer that maps high-level type safety wrappers directly to machine instructions. It utilizes static type identity enforcement to treat logically distinct data as incompatible types, even when they share the same underlying representation, and employs compact, union-based containers to manage optional values without heap allocation or metadata overhead.
The library covers a broad range of safety mechanisms, including custom constraints for validating value bounds and specialized wrappers for pointers and indices to prevent null errors. It also provides strict numeric enforcement to prevent accidental data loss or invalid arithmetic, while restricting primitive operations to ensure that variables maintain their intended state throughout the program.
Features

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
