Types

type Resolver

type Resolver struct {
	// contains filtered or unexported fields
}

Resolver uses notifier to fetch list of available hosts

func New

func New(
	notifier discovery.Notifier,
	discoverer discovery.Discoverer,
	logger *zap.Logger,
	discoveryMinPeers int,
) *Resolver

New initialize a new grpc resolver with notifier

func (*Resolver) Build

func (r *Resolver) Build(_ resolver.Target, cc resolver.ClientConn, _ resolver.BuildOptions) (resolver.Resolver, error)

Build returns itself for Resolver, because it's both a builder and a resolver.

func (*Resolver) Close

func (r *Resolver) Close()

Close closes both discoCh

func (*Resolver) ResolveNow

func (*Resolver) ResolveNow(resolver.ResolveNowOptions)

ResolveNow is a noop for Resolver since resolver is already firing r.cc.UpdatesState every time it receives updates of new instance from discoCh

func (*Resolver) Scheme

func (r *Resolver) Scheme() string

Scheme returns resolver's scheme.
