I've made an open-source library for using design by contract (DbC) principles in the Zig programming language.
It's called Zig-DbC, and it currently provides the following features:
- A simple API to define preconditions, postconditions, and invariants.
- Contracts are active in `Debug`, `ReleaseSafe`, and `ReleaseSmall` modes to catch bugs early.
- All checks are removed at compile time in `ReleaseFast` mode for zero performance cost.
- An optional mode to handle partial state changes in functions that return errors.
- Transparent error handling that propagates errors from your code to the caller.
