type FS …

// ValidPath reports whether the given path name
// is valid for use in a call to Open.
//
// Path names passed to open are UTF-8-encoded,
// unrooted, slash-separated sequences of path elements, like “x/y/z”.
// Path names must not contain an element that is “.” or “..” or the empty string,
// except for the special case that the root directory is named “.”.
// Paths must not start or end with a slash: “/x” and “x/” are invalid.
//
// Note that paths are slash-separated on all systems, even Windows.
// Paths containing other characters such as backslash and colon
// are accepted as valid, but those characters must never be
// interpreted by an [FS] implementation as path element separators.
