alt Hacker NewsPeople do have cold Rust compiles that can push up into measured in hours. Large crates often take design choices that are more compile time friendly shape.
Note that C++ also has almost as large problem with compile times with large build fanouts including on templates, and it's not always realistic for incremental builds to solve either especially time burnt on linking, e.g. I believe Chromium development often uses a mode with .dlls dynamic linking instead of what they release which is all static linked exactly to speed up incremental development. The "fast" case is C not C++.

There's no Rust codebase that takes hours to compile cold unless 1) you're compiling a massive codebase in release mode with LTO enabled, in which case, you've asked for it, 2) you've ported Doom to the type system, or 3) you're compiling on a netbook.

Bevy, a Rust ECS framework for building games (among other things), has a similar solution by offering a build/rust "feature" that enables dynamic linking (called "dynamic_linking"). https://bevy.org/learn/quick-start/getting-started/setup/#dy...
