--- Comment #13 from Maxwell G maxwell@gtmx.me --- I copied those env vars from %cargo_build. I'll try to remove RUSTC_BOOTSTRAP. As for CARGOHOME, https://pagure.io/fedora-rust/rust-packaging/blob/main/f/macros.d/macros.car... says:
# CARGO_HOME: This ensures cargo reads configuration file from .cargo/config, # and prevents writing any files to $HOME during RPM builds.
How are Python bindings written in Rust different in this regard?
