Functions

func GetMaxWeight 

func GetMaxWeight(
	chainState state.Chain,
	validator *state.Staker,
	startTime time.Time,
	endTime time.Time,
) (uint64, error)

GetMaxWeight returns the maximum total weight of the [validator], including its own weight, between [startTime] and [endTime]. The weight changes are applied in the order they will be applied as chain time advances. Invariant: - [validator.StartTime] <= [startTime] < [endTime] <= [validator.EndTime]

func GetNextStakerChangeTime 

func GetNextStakerChangeTime(state state.Chain) (time.Time, error)

GetNextStakerChangeTime returns the next time a staker will be either added or removed to/from the current validator set.

func GetValidator 

func GetValidator(state state.Chain, subnetID ids.ID, nodeID ids.NodeID) (*state.Staker, error)

GetValidator returns information about the given validator, which may be a current validator or pending validator.

Types

type AtomicTxExecutor 

type AtomicTxExecutor struct {
	// inputs, to be filled before visitor methods are called
	*Backend
	ParentID      ids.ID
	StateVersions state.Versions
	Tx            *txs.Tx

	// outputs of visitor execution
	OnAccept       state.Diff
	Inputs         ids.Set
	AtomicRequests map[ids.ID]*atomic.Requests
}

atomicTxExecutor is used to execute atomic transactions pre-AP5. After AP5 the execution was moved to be performed inside of the standardTxExecutor.
