It’s time to look at some of the progress on Rust compiler speed made since my last post in July. Metrics First, a note about metrics. The rustc benchmark suite uses several different time-related metrics, each of which has its pros and cons. Wall-time: this is the most realistic metric, because it exactly matches a user’s experience. But has high variance, which makes it poor for detecting small
When GHC 9.2 was released in late 2021, I was eager to migrate my projects, particularly to reap the ergonomic benefits of the record dot syntax feature. My disappointment was immeasurable as I discovered that some of my more involved type-level computations caused GHCi to get stuck, just spinning indefinitely at full CPU load – it meant that in order to get productive with the new compiler, I wou
Languages like C and C++ are standardized. They are fully specified in an internationally recognized standards document. Languages like Python, Swift and Rust do not have such a standards document. Should Rust be standardized? Why, or why not? In this blog post, I try to explain why I do think we need an accurate specification, why I do not think we need “standardization” (depending on your defini
There is no standard way to iterate over a sequence of values in Go. For lack of any convention, we have ended up with a wide variety of approaches. Each implementation has done what made the most sense in that context, but decisions made in isolation have resulted in confusion for users. In the standard library alone, we have archive/tar.Reader.Next, bufio.Reader.ReadByte, bufio.Scanner.Scan, con
