Package - Wire

The neo wire package will implement the network protocol displayed here: http://docs.neo.org/en-us/network/network-protocol.html

This package will act as a standalone package.

Responsibility

This package will solely be responsible for Encoding and decoding a Message. It will return a Messager interface, which means that the caller of the package will need to type assert it to the appropriate type.

Usage

Write Message

expectedIP := "127.0.0.1"
expectedPort := 8333
tcpAddrMe := &net.TCPAddr{IP: net.ParseIP(expectedIP), Port: expectedPort}
message, err := NewVersionMessage(tcpAddrMe, 0, true, defaultVersion)

conn := new(bytes.Buffer)
if err := WriteMessage(con, Production, message); err != nil {
	// handle Error
}

Read Message

readmsg, err := ReadMessage(conn, Production)

if err != nil {
	// Log error
}
version := readmsg.(*VersionMessage)

RoadMap

[ x ] CMDGetData (Tests Added)
[ x ] CMDBlock (Tests Added)
[ x ] CMDTX // Each tx implments the messager interface
[   ] CMDConsensus

Notes

Please not that this package will do sanity checks on the fields, however it will not verify if any of the items are valid for the current state of the system. Please see Responbilities.

The difference between Encode/Decode and EncodePayload/DecodePayload, is the parameter type. In most cases, Encode/Decode is just a convenience method.

Contributors

When modifying this package, please ensure that it does not depend on any other package and that it conforms to the Single Responsibility Principle. If you see somewhere in the current implementation that does not do this, then please tell me.
