Functions

func SetLookupTimeout

func SetLookupTimeout(t time.Duration) func()

SetLookupTimeout sets the node resolution lookup timeout.

Types

type Resolver

type Resolver interface {
	Type() string
	Addr() string
	GetAddress() (net.Addr, error)
	IsExhausted() bool
}

Resolver is an interface which provides an abstract factory for net.Addr addresses. Resolvers are not thread safe.

func NewResolver

func NewResolver(context *base.Context, spec string) (Resolver, error)

NewResolver takes a resolver specification and returns a new resolver. A specification is of the form: [<network type>=]<address> Network type can be one of:

• tcp: plain hostname or ip address
• unix: unix sockets
• http-lb: http load balancer: queries http(s)://<lb>/_status/details/local for node addresses

If "network type" is not specified, "tcp" is assumed.

func NewResolverFromAddress

func NewResolverFromAddress(addr net.Addr) (Resolver, error)

NewResolverFromAddress takes a net.Addr and constructs a resolver.

func NewResolverFromUnresolvedAddr

func NewResolverFromUnresolvedAddr(addr util.UnresolvedAddr) (Resolver, error)

NewResolverFromUnresolvedAddr takes a util.UnresolvedAddr and constructs a resolver.
