Struct embedded_sdmmc::RawDirectory

pub struct RawDirectory(/* 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.

Implementations

impl RawDirectory

pub fn to_directory<D, T, const MAX_DIRS: usize, const MAX_FILES: usize, const MAX_VOLUMES: usize>( self, volume_mgr: &mut VolumeManager<D, T, MAX_DIRS, MAX_FILES, MAX_VOLUMES> ) -> Directory<'_, D, T, MAX_DIRS, MAX_FILES, MAX_VOLUMES>

where D: BlockDevice, T: TimeSource,

Convert a raw directory into a droppable Directory

Trait Implementations

impl Clone for RawDirectory

fn clone(&self) -> RawDirectory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RawDirectory

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

Formats the value using the given formatter.

impl PartialEq for RawDirectory

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

This method tests for self and other values to be equal, and is used by ==.

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

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