Constants

const ConfigID = ControllerID

ConfigID is the identifier for the config type.

const ControllerID = "bifrost/pubsub/relay/1"

ControllerID is the ID of the controller.

Variables

var Version = semver.MustParse("0.0.1")

Version is the version of the controller implementation.

Types

type Config

type Config struct {
	// PeerId is the peer ID to look up and use private key for.
	PeerId string `protobuf:"bytes,1,opt,name=peer_id,json=peerId,proto3" json:"peer_id,omitempty"`
	// TopicIds are the list of topic IDs to subscribe to.
	TopicIds             []string `protobuf:"bytes,2,rep,name=topic_ids,json=topicIds,proto3" json:"topic_ids,omitempty"`
	XXX_NoUnkeyedLiteral struct{} `json:"-"`
	XXX_unrecognized     []byte   `json:"-"`
	XXX_sizecache        int32    `json:"-"`
}

Config is the pubsub relay configuration. The relay controller subscribes to a pubsub topic to ensure the peer relays messages.

func (*Config) Descriptor

func (*Config) Descriptor() ([]byte, []int)

func (*Config) EqualsConfig

func (c *Config) EqualsConfig(c2 config.Config) bool

EqualsConfig checks equality between two configs.

func (*Config) GetConfigID

func (c *Config) GetConfigID() string

GetConfigID returns the config identifier.

func (*Config) GetPeerId

func (m *Config) GetPeerId() string

func (*Config) GetTopicIds

func (m *Config) GetTopicIds() []string

func (*Config) ParsePeerID

func (c *Config) ParsePeerID() (peer.ID, error)

ParsePeerID parses the peer ID if it is not empty.

func (*Config) ProtoMessage

func (*Config) ProtoMessage()

func (*Config) Reset

func (m *Config) Reset()

func (*Config) String

func (m *Config) String() string

func (*Config) Validate

func (c *Config) Validate() error

Validate validates the configuration.

func (*Config) XXX_DiscardUnknown

func (m *Config) XXX_DiscardUnknown()

func (*Config) XXX_Marshal

func (m *Config) XXX_Marshal(b []byte, deterministic bool) ([]byte, error)

func (*Config) XXX_Merge

func (m *Config) XXX_Merge(src proto.Message)

func (*Config) XXX_Size

func (m *Config) XXX_Size() int

func (*Config) XXX_Unmarshal

func (m *Config) XXX_Unmarshal(b []byte) error

type Controller

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

Controller is the static Link establish controller. It adds a EstablishLink for each configured peer.

func NewController

func NewController(b bus.Bus, le *logrus.Entry, peerID peer.ID, topics []string) *Controller

NewController constructs a new relay controllr.

func (*Controller) Close

func (c *Controller) Close() error

Close releases any resources used by the controller. Error indicates any issue encountered releasing.

func (*Controller) Execute

func (c *Controller) Execute(ctx context.Context) error

Execute executes the given controller. Returning nil ends execution. Returning an error triggers a retry with backoff.

func (*Controller) GetControllerInfo

func (c *Controller) GetControllerInfo() controller.Info

GetControllerInfo returns information about the controller.

func (*Controller) HandleDirective

func (c *Controller) HandleDirective(
	ctx context.Context,
	di directive.Instance,
) (directive.Resolver, error)

HandleDirective asks if the handler can resolve the directive. If it can, it returns a resolver. If not, returns nil. Any exceptional errors are returned for logging. It is safe to add a reference to the directive during this call.

type Factory

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

Factory constructs a pubsub relay controller.

func NewFactory

func NewFactory(bus bus.Bus) *Factory

NewFactory builds a pubsub relay factory.

func (*Factory) Construct

func (t *Factory) Construct(
	conf config.Config,
	opts controller.ConstructOpts,
) (controller.Controller, error)

Construct constructs the associated controller given configuration.

func (*Factory) ConstructConfig

func (t *Factory) ConstructConfig() config.Config

ConstructConfig constructs an instance of the controller configuration.

func (*Factory) GetConfigID

func (t *Factory) GetConfigID() string

GetConfigID returns the configuration ID for the controller.

func (*Factory) GetControllerID

func (t *Factory) GetControllerID() string

GetControllerID returns the unique ID for the controller.

func (*Factory) GetVersion

func (t *Factory) GetVersion() semver.Version

GetVersion returns the version of this controller.
