Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Qt bindings for Rust also exist, although I'm not sure how mature they are: https://github.com/KDAB/cxx-qt/
