This was done using the unstable rustfmt option[1] group_imports that requires a nightly toolchain, thus it was run manually. [1]: https://rust-lang.github.io/rustfmt/?version=v1.8.0&search=import#group_imports Signed-off-by: Stefan Kerkmann <[email protected]>
mkdir, read_file write_file augment the error case with the path in the error case. This is useful as we otherwise don't know which location failed. This commit refactors the functions to take any argument that coerces into a Path - which is implemented by many types. mkdir now uses create_dir_all as it is not meant to fail if the directory already exists.

This looks wrong. In the else case, the string is converted multiple times.

Hmm, the file name read above is not necessarily UTF-8, so converting it into a String is technically not correct.

Unrelated, this should be a separate commit.

@michaelolbrich Thanks for having a look, the PR is still in draft and only a quick "hack job" at this point. |
