Expand description

Async filesystem primitives.

This crate is an async version of std::fs.

Implementation

This crate uses blocking to offload blocking I/O onto a thread pool.

Examples

Create a new file and write some bytes to it:

use async_fs::File;
use futures_lite::io::AsyncWriteExt;

let mut file = File::create("a.txt").await?;
file.write_all(b"Hello, world!").await?;
file.flush().await?;
