zig-comptime

Zig comptime enables generic programming by using `anytype` parameters, allowing the compiler to infer types and generate type-specific code at compile time. This creates flexible functions and data structures without runtime overhead.

Type reflection in Zig uses the `@typeInfo` builtin to inspect and analyze types at compile time. It returns a tagged union describing the type's structure, enabling conditional logic and code generation during compilation.

Zig metaprogramming uses comptime to execute code during compilation, providing type-safe code generation similar to C++ templates. It replaces macro-based generation with explicit compile-time evaluation and type reflection.

Yes, you can generate lookup tables at compile time in Zig. By executing loops and calculations within a comptime block, the results are pre-computed and embedded directly into the binary, eliminating runtime calculation overhead.

Use comptime parameters in Zig functions when values must be known at compilation to influence type generation or control flow. This allows the compiler to produce optimized, type-safe code tailored to specific compile-time constants.
