TmpDir

Useful to create temp directories and copying their contents on completion of some action. Tmp dirs will be created using [env::temp_dir] with some random characters prefixed to prevent a name clash

copy will traverse recursively through a directory and copy all file contents to some destination dir. It will not follow symlinks.

Example

```rust use tmpdir::TmpDir; use tokio::{fs, io::AsyncWriteExt};

let tmp = TmpDir::new("foo").await.unwrap(); let new_tmp = TmpDir::new("bar").await.unwrap();

newtmp.copy(tmp.asref()).await; new_tmp.close().await; // not necessary to explicitly call ```
