# This function is imported as `rustPackageOverlay` in `nix/overlays/default.nix`.
#
# Supplies a stable `rustPlatform` from `rust-bin` to `callPackage`.
# The `rust-overlay` must have already been composed onto the `pkgs` set.
#
# This prevents `rust-bin` from being an input of the package, which would
# make it less portable.
