It's sad that the solution is just copying pasting from &str with the only difference being that this returns owned values. I'm not blocking on this, but perhaps implementing ToOwned would be viable here?

Approving this =)

Yea. I agree with you. But since we are passing in an owned String, any variable created would not live long enough to return.

Do you have some reference as to how ToOwned will help and its implementation?

Essentially both &str and String implementations are basically the same except one returns Cow::Borrowed fields and the other returns Cow::Owned. Looking at the docs once more, AssetPath actually implements Clone.

Maybe asset_path.as_str().into().clone() would suffice?

I tried implementing using asset_path.as_str().into().clone() as below

And got the following error which I think is the same as asset_path.as_str().into()

cannot return value referencing function parameter asset_path
returns a value referencing data owned by the current function rustcE0515

Hmm. What if we go through the PathBuf route? According to the impl, converting from String to PathBuf shouldn't allocate memory, which is nice.

That is possible but we will lose the label of AssetPath as it's assigned a None to it.
