Types

type AddHandler

type AddHandler interface {
	AddHandler(name, desc string, args []string, handlerfunc AddHandlerFunc) error
}

type AddHandlerFunc

type AddHandlerFunc func(json.RawMessage) (interface{}, error)

type AllowedPublicKey

type AllowedPublicKey ed25519.PublicKey

type Core

type Core struct {
	// This is the main data structure that holds everything else for a node
	// We're going to keep our own copy of the provided config - that way we can
	// guarantee that it will be covered by the mutex
	phony.Inbox
	*iwe.PacketConn
	// contains filtered or unexported fields
}

The Core object represents the Ruvchain node. You should create a Core object for each Ruvchain node you plan to run.

func New

func New(cert *tls.Certificate, logger Logger, opts ...SetupOption) (*Core, error)

func (*Core) AddPeer

func (c *Core) AddPeer(u *url.URL, sintf string) error

AddPeer adds a peer. This should be specified in the peer URI format, e.g.:

tcp://a.b.c.d:e
socks://a.b.c.d:e/f.g.h.i:j

This adds the peer to the peer list, so that they will be called again if the connection drops.

func (*Core) Address

func (c *Core) Address() net.IP

Address gets the IPv6 address of the Ruvchain node. This is always a /128 address. The IPv6 address is only relevant when the node is operating as an IP router and often is meaningless when embedded into an application, unless that application also implements either VPN functionality or deals with IP packets specifically.

func (*Core) CallPeer

func (c *Core) CallPeer(u *url.URL, sintf string) error

CallPeer calls a peer once. This should be specified in the peer URI format, e.g.:

tcp://a.b.c.d:e
socks://a.b.c.d:e/f.g.h.i:j

This does not add the peer to the peer list, so if the connection drops, the peer will not be called again automatically.

func (*Core) GetPaths

func (c *Core) GetPaths() []PathEntryInfo

func (*Core) GetPeers

func (c *Core) GetPeers() []PeerInfo

func (*Core) GetSelf

func (c *Core) GetSelf() SelfInfo

func (*Core) GetSessions

func (c *Core) GetSessions() []SessionInfo

func (*Core) GetTree

func (c *Core) GetTree() []TreeEntryInfo

func (*Core) Listen

func (c *Core) Listen(u *url.URL, sintf string) (*Listener, error)

Listen starts a new listener (either TCP or TLS). The input should be a url.URL parsed from a string of the form e.g. "tcp://a.b.c.d:e". In the case of a link-local address, the interface should be provided as the second argument.

func (*Core) MTU

func (c *Core) MTU() uint64

func (*Core) PublicKey

func (c *Core) PublicKey() ed25519.PublicKey

func (*Core) ReadFrom

func (c *Core) ReadFrom(p []byte) (n int, from net.Addr, err error)

func (*Core) RemovePeer

func (c *Core) RemovePeer(u *url.URL, sintf string) error

RemovePeer removes a peer. The peer should be specified in URI format, see AddPeer. The peer is not disconnected immediately.

func (*Core) RetryPeersNow

func (c *Core) RetryPeersNow()

func (*Core) SetAdmin

func (c *Core) SetAdmin(a AddHandler) error

SetAdmin must be called after Init and before Start. It sets the admin handler for NodeInfo and the Debug admin functions.

func (*Core) SetLogger

func (c *Core) SetLogger(log Logger)

SetLogger sets the output logger of the Ruvchain node after startup. This may be useful if you want to redirect the output later. Note that this expects a Logger from the github.com/gologme/log package and not from Go's built-in log package.

func (*Core) SetPathNotify

func (c *Core) SetPathNotify(notify func(ed25519.PublicKey))

func (*Core) Stop

func (c *Core) Stop()

Stop shuts down the Ruvchain node.

func (*Core) Subnet

func (c *Core) Subnet() net.IPNet

Subnet gets the routed IPv6 subnet of the Ruvchain node. This is always a /64 subnet. The IPv6 subnet is only relevant when the node is operating as an IP router and often is meaningless when embedded into an application, unless that application also implements either VPN functionality or deals with IP packets specifically.

func (*Core) WriteTo

func (c *Core) WriteTo(p []byte, addr net.Addr) (n int, err error)

}
