assert2

assert!(...) and check!(...) macros inspired by Catch2.

This crate is currently a work in progress. It relies on a nightly compiler with the proc_macro_hygiene, proc_macro_span and specialization features.

As a user of the crate, you also need to enable the proc_macro_hygiene feature.

Example

```rust

![feature(procmacrohygiene)]

use assert2::check;

let mut vec = Vec::new(); vec.push(12);

check!(vec.len() == 2); check!(&vec == &vec![10]); ```
