Types

type Connector 

type Connector interface {

		ctx context.Context,
		nodeID ids.NodeID,
		nodeVersion *version.Application,
	) error
	Disconnected(ctx context.Context, nodeID ids.NodeID) error

Connector represents a handler that is called when a connection is marked as connected or disconnected

	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.

	// Returns err if subset weight overflows uint64.
	SubsetWeight(subnetID ids.ID, validatorIDs set.Set[ids.NodeID]) (uint64, error)

	// RemoveWeight from a staker in the subnet. If the staker's weight becomes 0, the staker
	// 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.
	RemoveWeight(subnetID ids.ID, nodeID ids.NodeID, weight uint64) error

	// Count returns the number of validators currently in the subnet.
	Count(subnetID ids.ID) int

	// TotalWeight returns the cumulative weight of all validators in the subnet.
	// Returns err if total weight overflows uint64.

	// Sample returns a collection of validatorIDs in the subnet, potentially with duplicates.
	// If sampling the requested size isn't possible, an error will be returned.
	Sample(subnetID ids.ID, size int) ([]ids.NodeID, error)

	// Map of the validators in this subnet
	GetMap(subnetID ids.ID) map[ids.NodeID]*GetValidatorOutput

	// will be notified of the event.
