Constants

View Source 
const DefaultBindAddress = "localhost:8080"

DefaultBindAddress is the default address that will be listened on. This default may not be used in managed cases when no bind address is explicitly set. In those cases the server will bind to all interfaces.

View Source 
const DefaultPackageVersionValue = "latest"

DefaultPackageVersionValue default value of the package version used when empty.

View Source 
const DefaultSessionHeartbeatWindow = 2 * time.Second

DefaultSessionHeartbeatWindow is the default session heartbeat window to use when not specified. It can be set with network.sessions.heartbeat_window.

Variables
