Constants

const ConfigID = ControllerID

ConfigID is the string used to identify this config object.

const ControllerID = "bifrost/stream/listening/1"

ControllerID identifies the listening controller.

Variables

var Version = semver.MustParse("0.0.1")

Version is the controller version.

}

Config configures the listening controller.

func (*Config) Descriptor

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

func (*Config) EqualsConfig

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

EqualsConfig checks if the config is equal to another.

func (*Config) GetConfigID

func (c *Config) GetConfigID() string

GetConfigID returns the unique string for this configuration type. This string is stored with the encoded config. Example: bifrost/transport/udp/1

func (m *Config) GetProtocolId() string

func (*Config) GetReliable

func (m *Config) GetReliable() bool

func (*Config) GetRemotePeerId

func (m *Config) GetRemotePeerId() string

func (*Config) GetTransportId

func (m *Config) GetTransportId() uint64

func (*Config) ParseListenMultiaddr

func (c *Config) ParseListenMultiaddr() (ma.Multiaddr, error)

ParseListenMultiaddr parses the multiaddress.

func (*Config) ParseLocalPeerID

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

ParseLocalPeerID parses the local peer ID. may return nil.

func (*Config) ParseRemotePeerID

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

ParseRemotePeerID parses the remote peer ID. may return nil.

func (*Config) ProtoMessage

func (*Config) ProtoMessage()

func (*Config) Reset

func (*Config) String

func (m *Config) String() string

func (*Config) Validate

func (c *Config) Validate() error

Validate validates the configuration. This is a cursory validation to see if the values "look correct."

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

type Controller

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

Controller implements the listening controller. The controller listens on a multiaddress and forwards incoming connections as streams to the target peer with the configured protocol ID attached.

func NewController

func NewController(
	le *logrus.Entry,
	conf *Config,
	bus bus.Bus,
) (*Controller, error)

NewController constructs a new listening controller.

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 listening 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.

type Factory

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

Factory constructs a listening controller

func NewFactory

func NewFactory(bus bus.Bus) *Factory

NewFactory builds a listening factory.

func (*Factory) Construct

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

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.
