Trait SaveKey 

pub trait SaveKey: Saves {
    type Value: SaveValue;

    // Required method
    fn fallback(&self) -> Self::Value;
}

One thing a game keeps between runs, named by a vocabulary of its own.

Required if you want save and saved to take a key: they read and keep its Value and nothing else. Every key of a vocabulary keeps the same kind of value; keys of another kind need a vocabulary of their own.

Required Associated Types

type Value: SaveValue

The value this key keeps, of the four a store takes.

Required Methods

fn fallback(&self) -> Self::Value

Value this key reads as before any run has saved it. Saving this value again leaves the key at the same fallback.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
