Types

type Connector 

type Connector interface {
	Connected(
		ctx context.Context,
		nodeID ids.NodeID,
		nodeVersion *version.Application,
	) error

	NodeID    ids.NodeID
	PublicKey *bls.PublicKey
	Weight    uint64
}

GetValidatorOutput is a struct that contains the publicly relevant values of a validator of the Avalanche Network for the output of GetValidator.

type Manager 

type Manager interface {
	fmt.Stringer

	// Add a new staker to the subnet.
	// Returns an error if:
	// - [weight] is 0
	// - [nodeID] is already in the validator set
	// If an error is returned, the set will be unmodified.
	AddStaker(subnetID ids.ID, nodeID ids.NodeID, pk *bls.PublicKey, txID ids.ID, weight uint64) error

	// AddWeight to an existing staker to the subnet.
	// Returns an error if:
	// - [weight] is 0
	// - [nodeID] is not already in the validator set
	// If an error is returned, the set will be unmodified.
	// AddWeight can result in a total weight that overflows uint64.
	// In this case no error will be returned for this call.
	// However, the next TotalWeight call will return an error.

	// GetWeight retrieves the validator weight from the subnet.

	// will be removed from the subnet set.
	// Returns an error if:
	// - [weight] is 0
	// - [nodeID] is not already in the subnet set
	// - the weight of the validator would become negative
	// If an error is returned, the set will be unmodified.
