Struct AsyncFile 

pub struct AsyncFile { /* private fields */ }

High-level async file handle

Provides async read/write operations with automatic statistics tracking.

Implementations

impl AsyncFile

pub async fn open<P: AsRef<Path>>(path: P, io: Arc<AsyncIo>) -> Result<Self>

Open a file for reading and writing (creates if not exists)

pub async fn open_read<P: AsRef<Path>>( path: P, io: Arc<AsyncIo>, ) -> Result<Self>

Open a file read-only

pub async fn read_at(&self, offset: u64, len: usize) -> Result<Bytes>

Async read at a specific offset

pub async fn write_at(&self, offset: u64, data: &[u8]) -> Result<usize>

Async write at a specific offset

pub async fn read(&self, len: usize) -> Result<Bytes>

Async read at current position (updates position)

pub async fn write(&self, data: &[u8]) -> Result<usize>

Async write at current position (updates position)

pub async fn sync(&self) -> Result<()>

Sync file to disk

pub fn seek(&self, pos: u64)

Seek to position

pub fn position(&self) -> u64

Get current position

pub async fn size(&self) -> Result<u64>

Get file size
