This blog post is about numeric units. Numbers in KCL are not just a number like 42 they always include units, e.g., 42mm. This is not unknown: F# has a famous and well-designed system, and more recently Swift added units. It is a bit diffe...
In May last year I wrote a blog post on how Rust had evolved from the 1.0 release to 1.78. I found it really interesting to group all the changes together by topic, rather than seeing the language evolve one release at a time. We're now at...
From a user's perspective an uncaught panic in a Rust program is a crash. A panic will terminate the thread and unless the developers have taken some care, that leads to the program terminating. This is not an exploitable crash and Rust usu...
How has Rust changed over the years? It's been nine years since 1.0 was released (well, next week, technically). In that time, there have been 78 major releases and two editions, with a third due later this year. Quite a lot has changed! Th...
Rust is an open source project. More than just the source code for the compiler being available, that means the project works in the open, inclusive of, and collaborating with, the wider community. That is sometimes difficult, especially wh...
The core team used to call for blog posts to help plan the next year. The core team has pretty much disappeared and certainly hasn't called for blog posts, but I'm going to write one anyway because I have opinions and I want you to hear the...
In response to the 'Call for blogs / ideas on Rust Foundation Strategy 2023-25', this post details where I think the Foundation should be headed over the next few years.I think we must start by considering the Foundation's relationship to t...
I had a good conversation with Ryan Levick (the core team's representative on the Foundation board) about my last blog post, between that and some more thinking, I'd like to refine and clarify some of what I said in the post.First off, a bu...
Error handling in Rust is a bit of an intermediate topic. That is in part because error handling in any language is actually more complicated than it seems, partly because it is a still-evolving part of the language and std libs (and theref...
The Rust project is run by its teams, such as the language team, library team, and community team. The teams are the primary structure for organising work and people in the Rust project, and effectively the only structure for governance. In...
Rust is in a pretty good place; it is getting more and more popular, has more and more contributors, and is used in some pretty significant places. However, it is a time of flux and change, and transitioning from a research project then a n...
In programming and programming language design we often talk about complexity. And for good reason! Complexity often feels like the enemy we are battling when learning a new codebase or new programming language, or just trying to debug some...
Completion-model IO systems don't work naturally with the Read trait. In this post I want to explore why that is and some alternatives. Many of the issues are related to cancellation, and there is some discussion ongoing around whether we c...
I think the Rust RFC process needs serious reform. In this blog post, I'll explain why I think that, by covering some of the problems with the current process.Before I get all negative, I think RFCs are amazing! They've been a crucial part...
Async programming in Rust is built on top of the operating system's async IO facilities. While it is possible to just use async/await for control flow, mostly people use async for async IO. The runtime and libraries abstract away many of th...
The Read and Write traits are key to IO in Rust and designing the async versions of these traits (and migrating runtimes to use them) is crucial for improving interoperability and portability in the async ecosystem. This work is part of ong...
In previous years, the core team have asked the community to write new years blog posts about Rust in the coming year. They haven't this year, but I wanted to write one anyway. However, it turned out to be harder than expected. Perhaps that...
I made a small crate for easy-to-use IO in Rust. It is called ezio, and 0.1 is released today. It is a simple crate and it is ready to use now. I expect it will evolve somewhat on the way to a 1.0 release, but there is nothing which should...
A goal of the async foundations working group is for async Rust to be portable and interoperable. I want to dig in to what that means in this blog post. For a little background, see my earlier post on async runtimes.To run async Rust code,...
"It's amazing how far const eval has come in #Rust. It wasn't too long ago that even a simple if/else wasn't permitted. Now we're not that far off from..."
