type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client is a wrapper over web socket neo-go client that provides smart-contract invocation interface and notification subscription functionality.

On connection lost tries establishing new connection to the next RPC (if any). If no RPC node available, switches to inactive mode: any RPC call leads to immediate return with ErrConnectionLost error, every notification consumer passed to any Receive* method is closed.

Working client must be created via constructor New. Using the Client that has been created with new(Client) expression (or just declaring a Client variable) is unsafe and can lead to panic.

func New 

func New(key *keys.PrivateKey, opts ...Option) (*Client, error)

New creates, initializes and returns the Client instance. Notary support should be enabled with EnableNotarySupport client method separately.

If private key is nil, it panics.

Other values are set according to provided options, or by default:

  • client context: Background;
  • dial timeout: 5s;
  • blockchain network type: netmode.PrivNet;
  • signer with the CalledByEntry scope;
  • wait interval: 500ms;
  • logger: &zap.Logger{Logger: zap.L()}.

If desired option satisfies the default value, it can be omitted. If multiple options of the same config value are supplied, the option with the highest index in the arguments will be used.
