Provides the TempFile
struct, an asynchronous wrapper based on tokio::fs
for temporary files that will be automatically deleted when the last reference to
the struct is dropped.
```rust use async_tempfile::TempFile;
async fn main() { let parent = TempFile::new().await.unwrap();
// The cloned reference will not delete the file when dropped.
{
let nested = parent.open_rw().await.unwrap();
assert_eq!(nested.file_path(), parent.file_path());
assert!(nested.file_path().is_file());
}
// The file still exists; it will be deleted when `parent` is dropped.
assert!(parent.file_path().is_file());
} ```
