dir-diff

Are the contents of two directories different?

Mostly useful for integration-style tests when you want to check some generated output.

Usage

Using dir-diff in an integration test with [tempdir]:

```rust,ignore extern crate dir_diff; extern crate tempdir;

[test]

fn smoketest() { let tmpdir = TempDir::new("foo").expect("create temp dir failed");

generate_some_stuff(&tmp_dir);

assert!(!dir_diff::is_different(&tmp_dir.path(), "path/to/fixture").unwrap());

} ```
