Types ¶
type Config ¶
type Config struct {
PeerKey ed25519.PrivateKey
DBPath string
BootNodes []*Node
Addr string
NetID network.ID
Self *Node
}
Config is the essential configuration to create a Discovery implementation
type Discovery ¶
type Discovery interface {
Start() error
Stop()
SubNodes(ch chan<- *Node, near bool)
UnSubNodes(ch chan<- *Node)
Mark(id NodeID, lifetime int64)
UnMark(id NodeID)
Block(id NodeID, ip net.IP)
More(ch chan<- *Node, n int)
Nodes() []string
Delete(id NodeID)
}
Discovery is the interface to discovery other node
type Message ¶
type Message interface {
String() string
// contains filtered or unexported methods
}
type Node ¶
type Node struct {
ID NodeID
IP net.IP
UDP uint16
TCP uint16
Net network.ID
Ext []byte
// contains filtered or unexported fields
}
Node mean a node in vite P2P network
func (*Node) Deserialize ¶
Deserialize encoded data, []byte, to a Node, you must create the Node first, like following:
n := new(Node) err := n.Deserialize(buf)
func (*Node) String ¶
String marshal node to url-like string which looks like:
vnode://<hex node id> vnode://<hex node id>@<ip>:<udpPort>#<tcpPort>
type NodeID ¶
type NodeID [32]byte
NodeID use to mark node, and build a structural network
var ZERO_NODE_ID NodeID
ZERO_NODE_ID is the zero-value of NodeID type
func Bytes2NodeID ¶
Bytes2NodeID turn a slice to NodeID
func HexStr2NodeID ¶
HexStr2NodeID parse a hex coded string to NodeID
func Priv2NodeID ¶
func Priv2NodeID(priv ed25519.PrivateKey) (NodeID, error)
Priv2NodeID got the corresponding NodeID from ed25519.PeerKey
