# File Diff
This module provides an atomic file diffing function for use in unit tests.
The diff\_files() function takes two file handles and determines returns true
if they point to identical files.
```rust
use file_diff::{diff_files};
use std::fs::{File};
let mut file1 = match File::open("./src/lib.rs") {
Ok(f) => f,
Err(e) => panic!("{}", e),
};
let mut file2 = match File::open("./src/lib.rs") {
Ok(f) => f,
Err(e) => panic!("{}", e),
};
diff_files(&mut file1, &mut file2);
```
The diff() function takes string representations of the files and returns true
if the strings represent real files and those files are identical.
```rust
use file_diff::{diff};
diff("./src/lib.rs", "./src/lib.rs"); // true
```
