          Python recognizes 'cryptography.hazmat.bindings._rust' as an 
importable package[^1],
          but it is absent from setuptools' `packages` configuration.

          This leads to an ambiguous overall configuration. If you want to 
distribute this
          package, please make sure that 'cryptography.hazmat.bindings._rust' 
is explicitly added
          to the `packages` configuration field.

          Alternatively, you can also rely on setuptools' discovery methods
          (for example by using `find_namespace_packages(...)`/`find_namespace:`
          instead of `find_packages(...)`/`find:`).

          You can read more about "package discovery" on setuptools 
documentation page:

https://setuptools.pypa.io/en/latest/userguide/package_discovery.html

          If you don't want 'cryptography.hazmat.bindings._rust' to be 
distributed and are
          already explicitly excluding 'cryptography.hazmat.bindings._rust' via
          `find_namespace_packages(...)/find_namespace` or 
`find_packages(...)/find`,
          you can try to use `exclude_package_data`, or 
`include-package-data=False` in
          combination with a more fine grained `package-data` configuration.

      If you are seeing a compilation error please try the following steps to
      successfully install cryptography:
      1) Upgrade to the latest pip and try again. This will fix errors for most
         users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
      2) Read https://cryptography.io/en/latest/installation/ for specific
         instructions for your platform.
      3) Check our frequently asked questions for more information:
         https://cryptography.io/en/latest/faq/
      4) Ensure you have a recent Rust toolchain installed:

  error: can't find Rust compiler

  If you are using an outdated pip version, it is possible a prebuilt wheel is 
available for this package but pip is not able to install from it. Installing 
from the wheel would avoid the need for a Rust compiler.

  To update pip, run:

      pip install --upgrade pip

  and then retry package installation.

  If you did intend to build this package from source, try installing a Rust 
compiler from your system package manager and ensure it is on the PATH during 
installation. Alternatively, rustup (available at https://rustup.rs) is the 
recommended way to download and update the Rust compiler toolchain.

  This package requires Rust >=1.48.0.
