Is it safe to delete Rust target folders?
Build output that Cargo creates in each Rust project, including compiled code, binaries and documentation.
Safe
Its owner recreates it by itself when it needs it, and nothing you made is lost.
~/
- Only next to Cargo.toml
- Never inside ~/
Library
What it is
Cargo writes everything it builds for a project, such as debug and release builds and generated documentation, into a target folder at the root of the project or workspace. It creates the folder again the next time you build, and your source code isn't affected. Target folders grow as dependencies, toolchains and build settings change, and can reach many gigabytes for large projects.
If it's removed
The next build of each project is a full, slower build. Programs you built are removed until you build them again.
How it's removed
Moved to the Trash, where you can restore it.
The free analyzer finds it and explains it. Removing it is Pro, after a review sheet that lists every move and command. It starts checked in the Cleanup checklist, except inside Documents or Desktop.
