Improve documentation on `createTransform()`

In current documentation about createTransform()
it unclear inboundState
and outboundState
parameters are full redux states to be serialized/deserialized or a value of a field of the state:
import { createTransform } from 'redux-persist';
const SetTransform = createTransform(
// transform state on its way to being serialized and persisted.
(inboundState, key) => {
// convert mySet to an Array.
return { ...inboundState, mySet: [...inboundState.mySet] };
},
// transform state being rehydrated
(outboundState, key) => {
// convert mySet back to a Set.
return { ...outboundState, mySet: new Set(outboundState.mySet) };
},
// define which reducers this transform gets called for.
{ whitelist: ['someReducer'] }
);
export default SetTransform;
As it turns out, each function has signature (fieldValue, key, state) => newValue
. I think the documentation should describe all three parameters. I can submit PR later
