# `EffectCell`

A container that runs an effect every time its data is mutated.
In essence, a slimed down implementation of the Observer pattern using Rust's `Fn` trait.

```rust
use effect_cell::EffectCell;

fn main() {
    let mut effect_cell = EffectCell::new(0);
    effect_cell.bind(|data| {println!("{data}");});
    effect_cell.update(1);
    // Prints "1"
}
```

## Operator Passthrough

The `XAssign` traits have been setup so that they can modify the internal data
without the need for a call through `update_lambda`.
They will always call effects.

```rust
use effect_cell::EffectCell;

fn main() {
    let mut effect_cell = EffectCell::new(0);
    effect_cell.bind(|data| {println!("{data}");});
    effect_cell += 1;
    // Prints "1"
}
```
