Struct NodeState

pub struct NodeState {
    pub node_id: u64,

Expand description

Represents the immutable state of a node.

For mutable state, use ValidatedState.

Fields§

§node_id: u64§chain_config: ChainConfig§l1_client: L1Client§state_catchup: Arc<dyn StateCatchup>§genesis_header: GenesisHeader§genesis_state: ValidatedState§l1_genesis: Option<L1BlockInfo>§coordinator: EpochMembershipCoordinator<SeqTypes>§epoch_height: Option<u64>§upgrades: BTreeMap<Version, Upgrade>

Map containing all planned and executed upgrades.

Currently, only one upgrade can be executed at a time. For multiple upgrades, the node needs to be restarted after each upgrade.

This field serves as a record for planned and past upgrades, listed in the genesis TOML file. It will be very useful if multiple upgrades are supported in the future.

§current_version: Version

Current version of the sequencer.

This version is checked to determine if an upgrade is planned, and which version variant for versioned types
to use in functions such as genesis. (example: genesis returns V2 Header if version is 0.2)
