The expect lint is really great, been looking forward to that for a while.

Still waiting for more flexible const generics ๐Ÿคž

fs::exists() was a nice little improvement that I didn't know about until I read this announcement.

It's a subtle difference between that and path::exists().

  • path::exists() == false might just mean you can't use it (if path::exists() cannot access a file due to e.g. permissions, it'll return false)
  • fs::exists() == Ok(false) means it's definitely not there (permissions error will cause an Err to be returned)
