@lolbinarycat hmm, you should probably either provide a godbolt link or specify things like the optimization level?

I guess that's because of inlining differences.

Even if more could be inlined in the From<PathBuf> for Box<Path>
case, it eventually delegates to Vec::shrink_to_fit
. This reminds me of similar issues where the optimizer struggles to reason about alloc
+realloc
pairs that can be coalesced down to a single alloc

While this problem does exist, it's not relevant here. This example is just inlining.
