Why Zig: A New Systems Language from a Go/Rust Perspective

Sun, 21 Jun 2026 09:15:00 +0800

This article is based on Zig 0.16 (released 2026-04-13, the latest stable release). Zig is a rapidly evolving modern systems programming language. Its source repository has moved from GitHub to Codeberg, and the official download page is at ziglang.org/download/.

Why Zig?

If you already know Go and Rust, you might ask: why look at a third systems language? The answer is simple: Zig fills the gap between Go and Rust.

Go conquered backend and cloud-native development with its low barrier to entry and high productivity. But its garbage collector (GC) and relatively large runtime become liabilities in low-level systems programming, embedded systems, and real-time scenarios. Rust delivers peak performance and safety through zero-cost abstractions and its ownership system, but its steep learning curve and slow compile times make it feel “heavy” for fast prototyping and small tools.

Basic Syntax: Ramp Up on Zig with Your Go/Rust Experience

This article is based on Zig 0.16.

In Part 1 we discussed why Zig is worth learning and how to run your first Hello World. Now it’s time to dive into the syntax—variables, types, control flow, functions, and generics. The single goal is to make you able to read and write Zig code.

If you have Go or Rust experience, none of these concepts will feel entirely new. I’ll draw comparisons at key points to help you map your existing knowledge.

Error Handling: A Third Way Beyond Go and Rust

Three Error Handling Paradigms

Error handling is one of the most debated topics in programming language design. Go’s multiple return values, Rust’s Result<T, E> enum, and Zig’s error union type represent three fundamentally different philosophies. This article assumes you have Go or Rust experience and uses that as a reference frame to understand Zig’s design.

Go: Multi-return + if err != nil

Go’s philosophy is “explicit over implicit” — functions can return multiple values, and the convention is that the last return value is error. Every call site must handle it:

Zig Memory Management: The Explicit Allocator Pattern

Wed, 24 Jun 2026 16:20:00 +0800

This article is based on Zig 0.16.

In the previous articles we covered Zig’s basic syntax and error handling. Now we arrive at the most distinctive part of Zig—memory management.

If you come from Go or Rust, Zig’s memory philosophy will feel unfamiliar: it provides neither garbage collection nor an ownership system. Instead, it chooses a fundamentally different path—the Allocator Pattern. The core convention is remarkably simple, yet far-reaching:

Any function that might allocate memory must accept a std.mem.Allocator parameter.

Zig Standard Library, the I/O Interface, and Concurrency: Tying It All Together

Fri, 26 Jun 2026 15:40:00 +0800

This article is based on Zig 0.16.

After five installments covering syntax, error handling, memory management, compile-time computation, and the build system — we’ve arrived at the finale. Time to tie it all together.

Version 0.16 is a convergence point of two major changes: the Unmanaged migration of standard library containers, and the introduction of the revolutionary std.Io interface. These transformations deeply affect how Zig code is written. This article explores both, closes with three-language comparison cases, and provides a learning roadmap and resources.
