pub fn open_files_under(dir: &Path) -> Vec<PathBuf>Expand description
Every file under dir this process has open, once per open descriptor or
handle. Directories are not files: a handle on one, the kind resolving a
path takes for a moment on Windows, holds no file open.
Panics if the directory cannot be resolved or enumeration fails. Descriptors
closed while being inspected may disappear from the result.
