bors b31f9cc22b Auto merge of #97178 - sunfishcode:ownedfd-and-dup, r=joshtriplett ... Add a `BorrowedFd::try_clone_to_owned` and accompanying documentation Add a `BorrowedFd::try_clone_to_owned`, which returns a new `OwnedFd` sharing the underlying file description. And similar for `BorrowedHandle` and `BorrowedSocket` on WIndows. This is similar to the existing `OwnedFd::try_clone`, but it's named differently to reflect that it doesn't return `Result<Self, ...>`. I'm open to suggestions for better names. Also, extend the `unix::io` documentation to mention that `dup` is permitted on `BorrowedFd`. This was originally requsted [here](https://github.com/rust-lang/rust/issues/88564#issuecomment-910786081). At the time I wasn't sure whether it was desirable, but it does have uses and it helps clarify the API. The documentation previously didn't rule out using `dup` on a `BorrowedFd`, but the API only offered convenient ways to do it from an `OwnedFd`. With this patch, the API allows one to do `try_clone` on any type where it's permitted.		2022-06-15 21:08:08 +00:00
