Struct OverlayDirectoryObject

pub struct OverlayDirectoryObject {
    overlay_fs: Arc<OverlayFS>,
    path: String,
    position: RwLock<u64>,
}

File object for OverlayFS directory operations

OverlayDirectoryObject handles reading directory entries from overlayfs, merging entries from upper and lower layers while respecting whiteout files.

Fields

overlay_fs: Arc<OverlayFS>

path: String

position: RwLock<u64>

Implementations

impl OverlayDirectoryObject

pub fn new(overlay_fs: Arc<OverlayFS>, path: String) -> Self

fn collect_directory_entries( &self, ) -> Result<Vec<DirectoryEntryInternal>, FileSystemError>

Collect all directory entries from all layers, handling whiteouts and merging

fn try_fs_from_mount( mount: &Arc<MountPoint>, ) -> Result<Arc<dyn FileSystemOperations>, FileSystemError>

Safe version of fs_from_mount that returns Result instead of panicking
