dittolive-ditto 4.9.3

//! A basic example showing how to insert Events into a Timeseries using the
//! RustSDK
//! Expects an App with ID, provided by env var $DITTO_APP_ID, to be properly
//! configured in the Ditto Cloud.
//! Further a valid DITTO_LICENSE must also be available (also provided by an
//! env var). Both can be obtained from `https://portal.ditto.live`
