[][src]Enum substrate_client::light::backend::GenesisOrUnavailableState

pub enum GenesisOrUnavailableState<H: Hasher> {
    Genesis(InMemoryState<H>),
    Unavailable,
}

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

Variants

Genesis(InMemoryState<H>)

Genesis state - storage values are stored in-memory.

Unavailable

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