Expand description
initializer struct for creating starting block
Fields§
§inner: Leaf<TYPES>
the leaf specified initialization
instance_state: TYPES::InstanceState
Instance-level state.
validated_state: Option<Arc<TYPES::ValidatedState>>
Optional validated state.
If it’s given, we’ll use it to construct the SystemContext
. Otherwise, we’ll construct
the state from the block header.
state_delta: Option<Arc<<TYPES::ValidatedState as ValidatedState<TYPES>>::Delta>>
Optional state delta.
If it’s given, we’ll use it to construct the SystemContext
.
start_view: TYPES::Time
Starting view number that should be equivelant to the view the node shut down with last.
actioned_view: TYPES::Time
The view we last performed an action in. An action is Proposing or voting for Either the quorum or DA.
high_qc: QuorumCertificate<TYPES>
Highest QC that was seen, for genesis it’s the genesis QC. It should be for a view greater
than inner
s view number for the non genesis case because we must have seen higher QCs
to decide on the leaf.
undecided_leafs: Vec<Leaf<TYPES>>
Undecided leafs that were seen, but not yet decided on. These allow a restarting node to vote and propose right away if they didn’t miss anything while down.
undecided_state: BTreeMap<TYPES::Time, View<TYPES>>
Not yet decided state
saved_proposals: BTreeMap<TYPES::Time, Proposal<TYPES, QuorumProposal<TYPES>>>
Proposals we have sent out to provide to others for catchup

Reload previous state based on most recent leaf and the instance-level state.
§Arguments
start_view
- The minimum view number that we are confident won’t lead to a double vote after restart.validated_state
- Optional validated state that if given, will be used to construct theSystemContext
.
