rust plugin: split RUSTUP_HOME and CARGO_HOME
Metadata
Current evaluation
Merged Rust plugin changes decoupling RUSTUP_HOME and CARGO_HOME. Previously both defaulted to ~/.cargo, risking side effects. They now point to ~/.rustup and ~/.cargo respectively. Approved and passed CI.
Suggested action: —
No scores available.
Issue body
RUSTUP_HOME is typically ~/.rustup
CARGO_HOME is typically ~/.cargo
They are both currently set to ~/.cargo.
It has been reported that overlapping the two may have side
effects. While I have not yet reproduced this, it's probably
a good idea to decouple the two directories anyways.
LP: #1852545
