Module Debug_protocol.Initialize_command

The 'initialize' request is sent as the first request from the client to the debug adapter in order to configure it with client capabilities and to retrieve capabilities from the debug adapter. Until the debug adapter has responded to with an 'initialize' response, the client must not send any additional requests or events to the debug adapter. In addition the debug adapter is not allowed to send any requests or events to the client until it has responded with an 'initialize' response. The 'initialize' request may only be sent once.
