Continuously read,write to disk, using random offsets and lengths. Adapted from random-access-storage/random-access-file.
```rust extern crate tempdir; extern crate randomaccessdisk;
use std::path::PathBuf; use tempdir::TempDir;
let dir = TempDir::new("random-access-disk").unwrap(); let mut file = randomaccessdisk::Sync::new(dir.path().join("README.db"));
file.write(0, b"hello").unwrap(); file.write(5, b" world").unwrap(); let _text = file.read(0, 11).unwrap(); ```
