Struct iota_types::iota_system_state::IotaSystemStateWrapper

pub struct IotaSystemStateWrapper {
    pub id: UID,
    pub version: u64,
}

Rust version of the Move iota::iota_system::IotaSystemState type This repreents the object with 0x5 ID. In Rust, this type should be rarely used since it’s just a thin wrapper used to access the inner object. Within this module, we use it to determine the current version of the system state inner object type, so that we could deserialize the inner object correctly. Outside of this module, we only use it in genesis snapshot and testing.

Fields

id: UID

version: u64

Implementations

impl IotaSystemStateWrapper

pub fn type_() -> StructTag

pub fn advance_epoch_safe_mode( &self, params: &AdvanceEpochParams, object_store: &dyn ObjectStore, protocol_config: &ProtocolConfig, ) -> (Object, Object)

Advances epoch in safe mode natively in Rust, without involking Move. This ensures that there cannot be any failure from Move and is guaranteed to succeed. Returns the old and new inner system state object.
