Llogiq on stuff 20 March 2026 I recently had a piece of code that used .to_lowercase() to sort some text. Which takes a bit of memory. On the plus side, the code used .sort_by_cached_key, which is pretty cool. But I wondered whether doing t...
Write small Rust scripts 05 March 2026 Recently I was working on a Rust PR to reduce unreachable_code lint churn after todo!() calls, that basically removes lint messages from unreachable_code after todo!() and instead adds a todo_macro_use...
Easy Mode Rust 28 March 2024 This post is based on my RustNationUK ‘24 talk with the same title. The talk video is on youtube, the slides are served from here. Also, here’s the lyrics of the song I introduced the talk with (sung to the tune...
Llogiq on stuff 19 February 2023 Update: The talk video is now on YouTube. The slides are here. As promised, here are some links and explanations to all the rhymes. First of all, the rap lyrics: My boss said this time I should try a Rust ra...
Llogiq on stuff 11 December 2022 It’s getting late in the year, so it’s time to write another blog post looking what good and bad came out of the year for Rust and what’s likely to happen next year. I guess the second part is also a roadmap...
Llogiq on stuff 30 December 2021 2021 was a great year for Rust. The language got more powerful. The standard library gained a good number of new functions and a lot of improvements on the existing ones. The error messages were tweaked and...
Llogiq on stuff 21 September 2020 This is my Rust 2021 post. I believe that Rust has shown that “bending the curve” is both possible and fruitful in programming language design. We also have a strong set of values as a community, enshrined...
Llogiq on stuff 30 May 2020 Recently I got into a discussion whether Rust is suitable as a high level language (First warning sign: Discussion, second: unclear meaning of terms). So I want to reproduce my argument here, hopefully to the ben...
Llogiq on stuff 14 March 2020 Rust’s generics give us a whole lot of flexibility. A method that takes a trait bound argument does not need to care about the actual type of the argument it is called with. For example: fn parse_read(r: impl R...
Llogiq on stuff 07 March 2020 Recently, I got yet another nice email from a “talent sourcing specialist” asking me if I’d like to work for their company. This one stood out from the usual blockchain recruiting spam by actually looking at th...
Llogiq on stuff 10 January 2020 My $dayjob is working in the cozy realms of Java, coddled by a GC and the amenities of a fat runtime. Common wisdom is to use a GC if you can afford it. I sometimes even write python if performance is a non-i...
Llogiq on stuff 01 January 2020 2019 was a great year for clippy. It’s available on stable, even installed by default in the Rust distribution and selectable as a rustup component. We have more than 300 lints, and the upwards trend is unbro...
Llogiq on stuff 28 October 2019 When I announced momo, I wanted its users to save both binary size and compile time while keeping their code simple. I succeeded in the first goal, but failed regarding the second. The reason was that momo re...
Causal Profiling Rust Code 25 September 2019 There’s a new hotness in performance measurements, and it’s called causal profiling. The idea behind it is that you want to measure how a speed up of a certain function would impact the runtime a...
Minimum Safe Abstractions 01 August 2019 Recently, there’s been a lot of talk about unsafe in the Rust world, and how to deal with it. Let’s recap: Rust has a subset called “safe Rust”, with a few very neat guarantees, such as memory safety...
Llogiq on stuff 18 May 2019 Monomorphization has one problem (apart from being a ridiculous word that I’ll probably spell wrong every time): It generates rather a lot of code, bloating binary size and potentially pessimizing execution cache...
Arenas vs. Indices 06 April 2019 When optimizing code, one thing I’m always looking for is memory layout and access patterns. One such pattern is an arena: Reserve some sufficiently large space to put your objects in, then allocate by incre...
Llogiq on stuff 08 December 2018 The Rust community team is soliciting blog posts to help plan the 2019 efforts. So here’s my take. I’ll start by looking back at the last year. We’ve seen great and impactful changes in the Rust landscape, s...
proc_macro_attribute Revisited 10 November 2018 Recently, the procedural macro interface was somewhat stabilized. OK, there’s still the unstable proc_macro_hygiene feature you have to activate, but at least the registrar and rustc_private a...
