snap_manageStateis currently the only way to manage state in a Snap. We added it as a single method initially, because it was complicated to add separate methods with a single permission. In addition,snap_manageStateonly supports operations on the entire state, it's not possible to get or set partial state.Instead, I've added new methods, which will eventually replace
snap_manageState. Thesnap_getStateandsnap_setStatemethods accept an optionalkey, which can be an object property-style key (e.g.,some.nested.value), and returns or updates the value at that location in the state. This makes it possible to do partial updates, or receive a small part of the state easily.Currently these methods require the
snap_manageStatepermission. In the future (when we removesnap_manageState) this could be replaced by an endowment.
