Implementations

impl Inode

pub fn new( block_id: u32, block_offset: usize, fs: Arc<Mutex<EasyFileSystem>>, block_device: Arc<dyn BlockDevice>, ) -> Self

Create a vfs inode

pub fn find(&self, name: &str) -> Option<Arc<Inode>>

Find inode under current inode by name

pub fn create(&self, name: &str) -> Option<Arc<Inode>>

Create inode under current inode by name. Attention: use find previously to ensure the new file not existing.

pub fn readdir(&self) -> Vec<String>

List inodes by id under current inode

pub fn read_at(&self, offset: usize, buf: &mut [u8]) -> usize

Read data from current inode

pub fn write_at(&self, offset: usize, buf: &[u8]) -> usize

Write data to current inode

pub fn clear(&self)

Clear the data in current inode
