[][src]Enum sc_service::client::light::backend::GenesisOrUnavailableState

pub enum GenesisOrUnavailableState<H: Hasher> {

Either in-memory genesis state, or locally-unavailable state.



Genesis state - storage values are stored in-memory.


We know that state exists, but all calls will fail with error, because it isn't locally available.
