Struct StateKey 

pub struct StateKey<T> { /* private fields */ }

A compile-time typed state key that eliminates typo bugs and type mismatches.

Create as a const and use with State::get_key() / State::set_key():

const TURN_COUNT: StateKey<u32> = StateKey::new("session:turn_count");
const SENTIMENT: StateKey<String> = StateKey::new("derived:sentiment");

state.set_key(&TURN_COUNT, 5);
let count: Option<u32> = state.get_key(&TURN_COUNT);
