Function rustc::util::fs::link_or_copy [] [src]

pub fn link_or_copy<P: AsRef<Path>, Q: AsRef<Path>>(p: P,
                                                    q: Q)
                                                    -> Result<LinkOrCopy>
🔬 This is a nightly-only experimental API. (rustc_private)

Copy p into q, preferring to use hard-linking if possible. If q already exists, it is removed first. The result indicates which of the two operations has been performed.
