Types ¶

type Resolver ¶

type Resolver struct {
	// BuildCallback is called when the Build method is called.  Must not be
	// nil.  Must not be changed after the resolver may be built.
	BuildCallback func(resolver.Target, resolver.ClientConn, resolver.BuildOptions)
	// ResolveNowCallback is called when the ResolveNow method is called on the
	// resolver.  Must not be nil.  Must not be changed after the resolver may
	// be built.
	ResolveNowCallback func(resolver.ResolveNowOptions)
	// CloseCallback is called when the Close method is called.  Must not be
	// nil.  Must not be changed after the resolver may be built.
	CloseCallback func()

	// Fields actually belong to the resolver.
	CC resolver.ClientConn
	// contains filtered or unexported fields
}

Resolver is also a resolver builder. It's build() function always returns itself.

func NewBuilderWithScheme ¶

func NewBuilderWithScheme(scheme string) *Resolver

NewBuilderWithScheme creates a new test resolver builder with the given scheme.

func (*Resolver) Build ¶

func (r *Resolver) Build(target resolver.Target, cc resolver.ClientConn, opts 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 is a noop for Resolver.

func (*Resolver) InitialState ¶

func (r *Resolver) InitialState(s resolver.State)

InitialState adds initial state to the resolver so that UpdateState doesn't need to be explicitly called after Dial.

func (*Resolver) ReportError ¶

func (r *Resolver) ReportError(err error)

ReportError calls CC.ReportError.

func (*Resolver) ResolveNow ¶

func (r *Resolver) ResolveNow(o resolver.ResolveNowOptions)

ResolveNow is a noop for Resolver.

func (*Resolver) Scheme ¶

func (r *Resolver) Scheme() string

Scheme returns the test scheme.

func (*Resolver) UpdateState ¶

func (r *Resolver) UpdateState(s resolver.State)

UpdateState calls CC.UpdateState.
