pub fn sync_dir(dir: &Utf8Path) -> Result<()>Expand description
Flush a directory entry, so a rename into it survives a crash.
A platform that refuses to sync a directory reports InvalidInput, and
there the ordering rests on the platform’s own semantics rather than on
a call this tool can make.
§Errors
Any I/O error other than a refusal to sync a directory at all.
