Functions

func CtxIdentity

func CtxIdentity(ctx context.Context) ([]byte, error)

CtxIdentity returns identity from context

func CtxPeerAddr

func CtxPeerAddr(ctx context.Context) string

CtxPeerAddr returns peer address

func CtxPeerClientVersion

func CtxPeerClientVersion(ctx context.Context) string

CtxPeerClientVersion returns peer client version

func CtxPeerId

func CtxPeerId(ctx context.Context) (string, error)

CtxPeerId first tries to get peer id under our own key, but if it is not found tries to get through DRPC key

func CtxProtoVersion

func CtxProtoVersion(ctx context.Context) (uint32, error)

CtxProtoVersion returns peer protocol version
