	// Name is the name of the pick_first_leaf balancer.

Functions

func EnableHealthListener

func EnableHealthListener(state resolver.State) resolver.State

EnableHealthListener updates the state to configure pickfirst for using a generic health listener.

func IsManagedByPickfirst

func IsManagedByPickfirst(addr resolver.Address) bool

IsManagedByPickfirst returns whether an address belongs to a SubConn managed by the pickfirst LB policy. TODO: https://github.com/grpc/grpc-go/issues/7915 - This is a hack to disable outlier_detection via the with connectivity listener when using pick_first. Once Dualstack changes are complete, all SubConns will be created by pick_first and outlier detection will only use the health listener for ejection. This hack can then be removed.
