Fluid Assertions in Rust

Example

Uses stainless for testing syntax

```rust describe! vec { describe! push { before_each { let mut v = vec![1u, 2, 3]; }

    it "should increase the length by 1" {
        let old = v.len();
        v.push(4u);
        // Fluid chain with informative error messages.
        (enforce!(old + 1)).is().equal(v.len());
    }

    it "should add another value to the end of the vec" {
        v.push(4u);
        // Has `some`, `none`, `ok`, and `err` methods for checking Option
        // and Result APIs.
        (enforce!(*v.get_mut(3))).is().some();
    }
}

} ```

Failed Assertion
