cargo clean does not clean downloaded crates

[carbotaniuman]

Problem

I tried to build a crate, but ran into an issue where a dependency was corrupted. I then tried to cargo clean the project, thinking that would fix it, but it didn't. I had to nuke my WSL and reinstall it to get the crate to build, losing a lot of time and effort.

Steps

Possible Solution(s)

cargo clean should also apply to dependencies, and not just the direct project.

See https://doc.rust-lang.org/nightly/cargo/guide/cargo-home.html#directories and unstable -Zgc feature if you want to manually remove source caches for now.

Assuming “downloaded crates” refer to downloaded source code resides under $CARGO_HOME/registry/{crate,src}, the design is tracked in #13060. Going to close this in favor of that. Please comment below if there is any reason keeping this issue open. Thank you.

Thanks for the pointers - I wish I'd have found those links sooner... I'm not sure my issue is directly related to the gc issue though - I would like to clean my dependencies entirely, not gc them depending on cache age.

Unlike some other build systems, dependency source is kept in a global cache while cargo clean is focused on your local cache. Think of the GC feature as a way for managing the global cache. The interface for doing so is not yet defined.
