Types

type Container

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

Container is a wrapper for the NNSResolver. It allows to update resolvers in runtime, without service restarting.

The Container should be used like regular NNSResolver.

func NewContainer

func NewContainer(ctx context.Context, endpoints []string) (*Container, error)

NewContainer is a constructor for the Container.

func (*Container) ResolveCID

func (r *Container) ResolveCID(ctx context.Context, name string) (cid.ID, error)

ResolveCID looks up the container id by its name via NNS contract. The method calls inline resolver.

func (*Container) UpdateResolvers

func (r *Container) UpdateResolvers(ctx context.Context, endpoints []string) error

UpdateResolvers allows to update resolver in runtime. Resolvers will be created from scratch.

type NNSResolver

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

NNSResolver allows to resolve container id by its name.

func NewNNSResolver

func NewNNSResolver(readers []*rpcNNS.ContractReader) *NNSResolver

NewNNSResolver is a constructor for the NNSResolver.

func NewResolver

func NewResolver(ctx context.Context, endpoints []string) (*NNSResolver, error)

NewResolver returns resolver depending on corresponding endpoints.

If endpoint is empty, error will be returned.

func (*NNSResolver) ResolveCID

func (r *NNSResolver) ResolveCID(_ context.Context, name string) (cid.ID, error)

ResolveCID looks up the container id by its name via NNS contract.
