Types

type AddrsFactory

type AddrsFactory = bhost.AddrsFactory

AddrsFactory is a function that takes a set of multiaddrs we're listening on and returns the set of multiaddrs we should advertise to the network.

type Config

type Config struct {
	PeerKey crypto.PrivKey

	Transports         []TptC
	Muxers             []MsMuxC
	SecurityTransports []MsSecC
	Insecure           bool
	Protector          pnet.Protector

	RelayCustom bool
	Relay       bool
	RelayOpts   []circuit.RelayOpt

	ListenAddrs  []ma.Multiaddr
	AddrsFactory bhost.AddrsFactory
	Filters      *filter.Filters

	ConnManager ifconnmgr.ConnManager
	NATManager  NATManagerC
	Peerstore   pstore.Peerstore
	Reporter    metrics.Reporter

	DisablePing bool
}

Config describes a set of settings for a libp2p node

This is *not* a stable interface. Use the options defined in the root package.

func (*Config) Apply

func (cfg *Config) Apply(opts ...Option) error

Apply applies the given options to the config, returning the first error encountered (if any).

func (*Config) NewNode

func (cfg *Config) NewNode(ctx context.Context) (host.Host, error)

NewNode constructs a new libp2p Host from the Config.

This function consumes the config. Do not reuse it (really!).

type MsMuxC

type MsMuxC struct {
	MuxC
	ID string
}

MsMuxC is a tuple containing a multiplex transport constructor and a protocol ID.

type MsSecC

type MsSecC struct {
	SecC
	ID string
}

MsSecC is a tuple containing a security transport constructor and a protocol ID.

type MuxC

type MuxC func(h host.Host) (mux.Transport, error)

MuxC is a stream multiplex transport constructor

func MuxerConstructor

func MuxerConstructor(m interface{}) (MuxC, error)

MuxerConstructor creates a multiplex constructor from the passed parameter using reflection.

type NATManagerC

type NATManagerC func(inet.Network) bhost.NATManager

NATManagerC is a NATManager constructor.

type Option

type Option func(cfg *Config) error

Option is a libp2p config option that can be given to the libp2p constructor (`libp2p.New`).

type SecC

type SecC func(h host.Host) (security.Transport, error)

SecC is a security transport constructor

func SecurityConstructor

func SecurityConstructor(sec interface{}) (SecC, error)

SecurityConstructor creates a security constructor from the passed parameter using reflection.

type TptC

type TptC func(h host.Host, u *tptu.Upgrader) (transport.Transport, error)

TptC is the type for libp2p transport constructors. You probably won't ever implement this function interface directly. Instead, pass your transport constructor to TransportConstructor.

func TransportConstructor

func TransportConstructor(tpt interface{}) (TptC, error)

TransportConstructor uses reflection to turn a function that constructs a transport into a TptC.

You can pass either a constructed transport (something that implements `transport.Transport`) or a function that takes any of:

* The local peer ID. * A transport connection upgrader. * A private key. * A public key. * A Host. * A Network. * A Peerstore. * An address filter. * A security transport. * A stream multiplexer transport. * A private network protector.

And returns a type implementing transport.Transport and, optionally, an error (as the second argument).
