The best guard for your architecture is probably already in your CI. You just use it for licenses. Architecture rules erode, whether people or agents write the code. With agents it's faster: the rule sits in the docs, the docs fall out of the context window, and the next shortcut compiles just fine. Let's make it stop compiling.

When designing error types in Rust, especially for libraries with a public API, there are several important considerations to keep in mind. This post will explore some of the important implications and common pitfalls when designing error types in Rust libraries. Further, we will look at thiserror and how the Rust standard library's std::io::Error can serve as a reference for designing your own error types.

In this post, we will explore the CIDR trie data structure and how it can help you manage IP addresses and subnets in your Rust project.

the AsRef trait is everywhere in the std lib and very handy. However, the benefit using it is maybe not too obvious. But read on, and you will see some useful examples and where to apply it.
