Appendix C. Common Compiler Errors

One of Zig’s strengths is compiler diagnostics. Zig tries to explain problems precisely instead of silently accepting dangerous behavior.

Appendix D. Important Standard Library APIs

Zig’s standard library is imported with:

Appendix E. Memory Safety Checklist

Zig gives you direct control over memory. That control is useful, but it also means you must follow clear rules.

Appendix F. Build Modes Reference

When Zig compiles a program, it can build the program in different modes.

Appendix G. C Interop Reference

Zig is designed to work closely with C. You can call C from Zig, call Zig from C, compile C code with Zig, and link Zig programs against existing C libraries.

Appendix H. Useful Open Source Zig Projects

This appendix lists useful Zig projects to read after you know the basics.

Appendix I. Zig Coding Style Guide

Zig code should be explicit, simple, and easy to inspect. The goal is not cleverness. The goal is code that another programmer can read, verify, and maintain.

Appendix J. Migrating Between Zig Versions

Zig is still before 1.0, so the language and standard library can change between releases. Code written for one Zig version may not compile on another version without edits.
