Each Rust project's target/ directory can easily hit 5-15GB. If you have 10 projects on your machine, that's 50-150GB of disk space consumed by build artifacts alone. On a 256GB or 512GB MacBook, that's a significant chunk of your drive gone to compiled code you probably aren't actively using. This isn't a bug. It's a direct consequence of how Rust's compilation model works — and once you understand the mechanics, you can make informed decisions about what to clean and how to prevent the bloat from coming back. Why Rust Builds Are So Large Rust's compilation strategy optimizes for correctness and runtime performance at the cost of disk space. Several factors compound to produce those multi-gigabyte target/ directories. Debug Info By default, cargo build produces a debug build. The compiler embeds full DWARF debug information into every binary and library artifact — function names, variable locations, type definitions, line number mappings.…
