There was a problem hiding this comment.
Instead of using to_owned for "unknown", taking a reference, then using again .to_owned a second time (2 allocations in the case of "unknown"), you should be able to invert that with the following code, isn’t it ?
Suggested change
| .unwrap_or(&"unknown".to_owned()) | |
| .to_owned(); | |
| .map(ToOwned::to_owned) | |
| .unwrap_or("unknown".to_owned()); |
And also, maybe returning a NonBlankString directly from this function would make it more obvious why the default value is "unknown" and not "".
Suggested change
| .unwrap_or(&"unknown".to_owned()) | |
| .to_owned(); | |
| .map(NonBlankString::from) | |
| .unwrap_or(NonBlankString::from("unknown")); |
