Struct sel4_async_block_io_fat::filesystem::Directory

pub struct Directory(/* private fields */);

Represents an open directory on disk.

Do NOT drop this object! It doesn’t hold a reference to the Volume Manager it was created from and if you drop it, the VolumeManager will think you still have the directory open, and it won’t let you open the directory again.

Instead you must pass it to [crate::VolumeManager::close_dir] to close it cleanly.

If you want your directories to close themselves on drop, create your own Directory type that wraps this one and also holds a VolumeManager reference. You’ll then also need to put your VolumeManager in some kind of Mutex or RefCell, and deal with the fact you can’t put them both in the same struct any more because one refers to the other. Basically, it’s complicated and there’s a reason we did it this way.

Trait Implementations

impl Clone for Directory

fn clone(&self) -> Directory

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Directory

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Directory

fn eq(&self, other: &Directory) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
