Allows replacing all keys from [`SYMBOL_MAP`] and (if provided) [`State`] with associated values.

Accessor for global state. Also works as state value for functions that accept [`OptionalState`] or [`OptionalStateMut`].

Much like [`AsRef`], but returns [`Option<StateRead<'s>>`] for different types. Consuming function decides whether to fallback to global state or not

Much like [`AsMut`], but returns [`Option<StateWrite<'s>>`] for different types. Consuming function decides whether to fallback to global state or no

Does the same as [str::replace], only for `byte`s intead of `char`s.
