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.
[`blocking`]: https://docs.rs/blocking
## Examples
Create a new file and write some bytes to it:
```rust
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?;
```
