folder_compare
=========================
A library to recursively compare files in two folders and return two lists of files: One with exclusive Files for the first folder one list with changed files between folders.

`folder_compare` also takes a list of Strings acting as exclude patterns using `RegexSet`.

Overall the functionality is comparable to a `diff -rq folder1 folder2 -X excludepatterns.pat` on unix like systems

For recognizing changed files, hashing with `FxHasher` is used.

### Usage

Add `folder_compare` as a dependency to your project's
`Cargo.toml`:

```toml
[dependencies]
folder_compare = "0.3"
```

 # Example

 The following code recursively iterates over two directories and returns lists of changed and new files excluding those with ".doc" and ".txt" as part of the name/path.

```
use std::path::Path;
use folder_compare;

let excluded = vec![".doc".to_string(), ".txt".to_string()];
let result = FolderCompare::new(Path::new("/tmp/a"), Path::new("/tmp/b"), &excluded).unwrap();

let changed_files = result.changed_files;
let new_filed = result.new_files;
```
