VfDir

Enum VfDir 

Source
#[non_exhaustive]
pub enum VfDir { Descriptor { fd: i32, owner: u64, }, Path(PathBuf), }
Expand description

An opaque handle to an open directory.

It exists so recursive removal can be rooted at an already-resolved directory instead of a path. Path-based entry points re-resolve the path and are therefore subject to the classic entry-point TOCTOU race: a concurrent actor can replace a path component with a symlink between the caller naming the path and the removal starting. A handle removes that race for the root of the removal (the same guarantee remove_dir_all’s RemoveDir trait gives). Backends without directory handles return VfDir::Path, which carries no such guarantee.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Descriptor

A backend-assigned directory handle, bound to the client that opened it.

Fields

§fd: i32
§owner: u64
§

Path(PathBuf)

A backend without directory handles; the removal re-resolves this path.
