Functions

func Add 

func Add(m Manager, subnetID ids.ID, nodeID ids.NodeID, pk *bls.PublicKey, txID ids.ID, weight uint64) error

Add is a helper that fetches the validator set of [subnetID] from [m] and adds [nodeID] to the validator set. Returns an error if: - [subnetID] does not have a registered validator set in [m] - adding [nodeID] to the validator set returns an error

func AddWeight 

func AddWeight(m Manager, subnetID ids.ID, nodeID ids.NodeID, weight uint64) error

AddWeight is a helper that fetches the validator set of [subnetID] from [m] and adds [weight] to [nodeID] in the validator set. Returns an error if: - [subnetID] does not have a registered validator set in [m] - adding [weight] to [nodeID] in the validator set returns an error

func Contains 

func Contains(m Manager, subnetID ids.ID, nodeID ids.NodeID) bool

Contains is a helper that fetches the validator set of [subnetID] from [m] and returns if the validator set contains [nodeID]. If [m] does not contain a validator set for [subnetID], false is returned.

func RemoveWeight 

func RemoveWeight(m Manager, subnetID ids.ID, nodeID ids.NodeID, weight uint64) error

RemoveWeight is a helper that fetches the validator set of [subnetID] from [m] and removes [weight] from [nodeID] in the validator set. Returns an error if: - [subnetID] does not have a registered validator set in [m] - removing [weight] from [nodeID] in the validator set returns an error
