# meta_tuple

A statically typed opaque tuple that can contain any type.

## Use Case

This crate is generally used for complicated input and output abstractions, for example

```rust
pub trait CardComponent {
    fn play(&self, input: &impl MetaTuple) -> impl MetaTuple;
}

impl CardComponent for Attack {
    fn play(&self, input: &impl MetaTuple) -> impl MetaTuple {
        let attacker = input.get::<Attacker>().unwrap();
        let defender = input.get::<Defender>().unwrap();
        let damage_dealt = self.calculate_damage(attacker, defender);
        input.join(DamageDealt(damage_dealt))
    }
}

pub trait CardComponent {
    pub fn play(&self, input: &impl MetaTuple) -> impl MetaTuple;
}
```
