Reminder that people see different things depending on what the alternative is: https://blog.rust-lang.org/2026/03/20/rust-challenges/ says that every cohort complains about Rust compile times. However, for me, Rust speeds up the compile&debug cycle compared to C++. It’s impractical to compile a piece of Gecko C++ separately from Firefox, so with C++, I have to compile Firefox as a whole and when upload a recording of excecuting Firefox as a whole to Pernosco. With Rust, I can typically iterate on a component separately.
