Rust Blog

A new blog post by developer Matt Keeter walks through testing WebGPU data layouts using Facet, a Rust library for reflecting on data structure memory layouts. Correct alignment and padding of buffers is a recurring pain point when passing data from CPU-side code to GPU shaders, and the post shows how reflection can verify that Rust structs match what the GPU expects.

Nicholas Nethercote, a longtime Rust compiler contributor, published a monthly write-up on his blog detailing performance improvements to rustc. The September 2026 post outlines the optimisations, profiling work and cleanup patches that reduced compile times, continuing his regular series on making the Rust compiler faster. Readers on Hacker News are discussing the findings.
