Enum NodeKind 

#[non_exhaustive]
pub enum NodeKind {
    Dir,
    RegularFile,
    NotFollowable {
        tag: Option<u32>,
    },
    NotAFile,
}

What a child is, decided without following it.

#[non_exhaustive], and every reader must match with a catch-all arm that refuses. A variant added later for diagnostics has to fail closed on every existing reader rather than fall into an is_dir()-shaped assumption.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Dir

RegularFile

NotFollowable

Symlink, NTFS junction, app-exec-link, WCI layer, OneDrive placeholder, or any other reparse tag.

One variant on purpose. The Windows trap is that a junction reports is_symlink() == false and is_dir() == true, so any type that lets a caller tell “symlink” from “some other reparse point” invites the wrong branch. There is no branch here to get wrong.

Fields

tag: Option<u32>

NotAFile

FIFO, socket, device, NUL, a named pipe — anything a read would block on, or that is not a file at all.
