[pbs-devel] [PATCH proxmox-backup 2/5] tape: replace '&Path' with 'AsRef<Path>' in function parameters
Dominik Csapak
d.csapak at proxmox.com
Thu May 19 12:08:17 CEST 2022
this way we can omit the pattern
```
let status_path = Path::new(TAPE_STATUS_DIR);
some_function(status_path);
```
and give the TAPE_STATUS_DIR directly. In some instances we now have to
give TAPE_STATUS_DIR more often, but most often we save a few
intermediary Paths.
