Implementations

impl Directory

pub const SIZE: usize

pub const fn new_empty() -> Self

pub fn as_bytes(&self) -> &[u8]

pub fn is_empty( inode: &Inode, inner: &mut SleepLockGuard<'_, InodeInner>, ) -> bool

Checks whether the directory is empty (only contains . and ..).

pub fn lookup( inode: &Inode, inner: &mut SleepLockGuard<'_, InodeInner>, name: &str, ) -> Result<Option<(u32, Inode)>, FsError>

Looks up for a directory entry in a directory. If found, returns byte offset and Inode.

pub fn link( inode: &Inode, inner: &mut SleepLockGuard<'_, InodeInner>, name: &str, inum: u16, ) -> Result<(), FsError>

Writes a new directory entry (name, inum) into the directory Inode.
