Trait Persisted 

pub trait Persisted:
    Clone
    + Send
    + Sync
    + 'static {
    // Required methods
    fn load(key: &str, fallback: Self) -> Self;
    fn store(key: &str, value: &Self);
}

A type UserDefaults can hold, and that a binding can therefore persist.

The four AppStorage supports without a RawRepresentable detour.

Required Methods

fn load(key: &str, fallback: Self) -> Self

The stored value, or fallback when nothing is stored.

fn store(key: &str, value: &Self)

Write, replacing whatever was there.

Dyn Compatibility

This trait is not dyn compatible.

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