Types

type PubsubValueStore

type PubsubValueStore struct {
	Validator record.Validator
	// contains filtered or unexported fields
}

func NewPubsubValueStore

func NewPubsubValueStore(ctx context.Context, host p2phost.Host, cr routing.ContentRouting, ps *floodsub.PubSub, validator record.Validator) *PubsubValueStore

NewPubsubPublisher constructs a new Publisher that publishes IPNS records through pubsub. The constructor interface is complicated by the need to bootstrap the pubsub topic. This could be greatly simplified if the pubsub implementation handled bootstrap itself

func (*PubsubValueStore) Cancel

func (p *PubsubValueStore) Cancel(name string) bool

Cancel cancels a topic subscription; returns true if an active subscription was canceled

func (*PubsubValueStore) GetSubscriptions

func (p *PubsubValueStore) GetSubscriptions() []string

GetSubscriptions retrieves a list of active topic subscriptions

func (*PubsubValueStore) GetValue

func (p *PubsubValueStore) GetValue(ctx context.Context, key string, opts ...ropts.Option) ([]byte, error)

func (*PubsubValueStore) PutValue

func (p *PubsubValueStore) PutValue(ctx context.Context, key string, value []byte, opts ...ropts.Option) error

Publish publishes an IPNS record through pubsub with default TTL

func (*PubsubValueStore) Subscribe

func (p *PubsubValueStore) Subscribe(key string) error
