# Some notes here:
# 1. All these --mount... are to cache reusable info between runs.
# See https://doc.rust-lang.org/cargo/guide/cargo-home.html#caching-the-cargo-home-in-ci
# 2. We add `--config net.git-fetch-with-cli=true` to address ARM build issue,
# see https://github.com/rust-lang/cargo/issues/10781#issuecomment-1441071052
# 3. To preserve space on github cache, we call `cargo clean`.
