Semantic Versioning

This project follows Semantic Versioning 2.0.0.

Currently the version is below 1.0.0 meaning that everything is very much unstable and the API could change completely.

Cargo Features

• time-slicing (default): A task runs at max for one system tick period if there are other tasks of equal priority
• log-defmt: Activate system log messages using defmt. The user must select a log transport in the application, e.g. defmt-rtt.
• log-rtt: Activate system log messages with core formatting and RTT transport.
• log-global: Activate system log messages using the log facade. The use must provide a global logger.
