Interfaces in Zig

Sun, 01 Feb 2026 00:00:00 +0000

Zig does not have an interface keyword — and that’s a feature, not a bug.

Zig’s design deliberately avoids baking object-oriented abstractions into the language. Instead, it gives you a small set of powerful primitives — structs, pointers, comptime, and function pointers — and lets you decide when abstraction is worth the cost.

Yet if you look closely at Zig’s standard library, you’ll quickly notice something interesting: interfaces are core to several commonly used parts of the standard library.

Using C libraries in Zig

Sat, 08 Nov 2025 00:00:00 +0000

Hey, everyone! Welcome to this tutorial where we'll explore one of Zig's most powerful features. Today, we're going to see how easy it is to use existing C libraries directly from Zig code.

Why C Interoperability Matters

One of the things that got me really excited about a different language, Clojure, when I was learning it was that although the Clojure ecosystem felt small, I had interoperability with anything that ran on the JVM. So you could interop with Java, Scala, eventually Kotlin after Kotlin really kind of caught on. It was great.

Zig's release modes

Tue, 09 Sep 2025 00:00:00 +0000

One of the first things I bumped into when I started writing Zig was its release modes. At first I thought: do I really need four different ways to compile my code? But as I dug in, I realized that release modes are one of Zig’s most practical features. They let you explicitly choose between safety, speed, and binary size — depending on whether you’re prototyping, testing, or shipping.

In this post, I’ll walk you through each release mode in detail, show you how they differ, and benchmark a simple Zig program across them.

Writing a B+ Tree in Zig

Sun, 06 Jul 2025 00:00:00 +0000

When building an embedded database, one of the most critical decisions is choosing the right data structure for storage and retrieval. After implementing a complete B+ tree from scratch in Zig for LowkeyDB, I want to share the journey, the challenges, and the (hopefully) elegant solutions that emerged.

What is a B+ Tree and Why Should You Care?

A B+ Tree is a self-balancing tree data structure that maintains sorted data and allows searches, sequential access, insertions, and deletions in logarithmic time. It's the backbone of most modern database systems, including PostgreSQL, MySQL, and SQLite.

Adding dependencies to your Zig project with zig fetch

Sun, 15 Dec 2024 00:00:00 +0000

Boy, does this feel like a weird blog post to write. I had to dig into the source code for the Zig cli to figure out how to do this, so I'm going to write about this and hopefully spare others from that pain.

Zig is a fun language and there's something ~~sexy~~ ~~powerful~~ ~~dangerous~~ enjoyable about having control of how memory is allocated. However, as with any language that I'm learning in my spare time, I don't want to have to write everything from scratch. I'd like to use the code written by others.
