# `EffectCell`

A container that runs an effect every time its data is mutated.
The effect is run with the old data.

You can mutate an `EffectCell` using the `update` method or the ~fancy~
`cell <<= val` syntax.

`EffectCell` does is also `#![no_std]`!

```rust
use effect_cell::EffectCell;

fn main() {
    let mut counter = 0;
    let mut printer = EffectCell::new(0, |_| counter += 1);
    printer <<= 2; // counter increments
    printer <<= 4; // counter increments
    assert_eq!(counter, 2)
}
```
