Zig Best Practices Type-First Development Types define the contract before implementation. Follow this workflow: 1. Define data structures - structs, unions, and error sets first 2. Define function signatures - parameters, return types, and error unions 3. Implement to satisfy types - let the compiler guide completeness 4. Validate at comptime - catch invalid configurations during compilation Make Illegal States Unrepresentable Use Zig's type system to prevent invalid states at compile time.
