The typing for PersistedState is not accurate in my opinion, which leads to this error:
ERROR in [at-loader] ./src/index.tsx:36:5
TS2345: Argument of type 'Reducer<(State & void) | (State & { _persist: PersistState; })>' is not assignable to parameter of type 'Reducer<State>'.
Types of parameters 'state' and 'state' are incompatible.
Type 'State' is not assignable to type '(State & void) | (State & { _persist: PersistState; })'.
Type 'State' is not assignable to type 'State & { _persist: PersistState; }'.
Type 'State' is not assignable to type '{ _persist: PersistState; }'.
Property '_persist' is missing in type 'State'.
[...]
export interface PersistState { version: number; rehydrated: boolean; }
export type PersistedState = { _persist: PersistState } | void;
export interface PersistConfig {

I will create a pull-request.
