/// The purpose of this module is to provide a common base for
/// implementing a shared fuzzed backend for the various traits.
///
/// The reasoning for this is to ensure that each call to a HAL
/// trait corresponds to a unique point in the fuzzing data. e.g.
/// The fuzzed result from an InputPin API should pull from the
/// same set of data as a call to the SPI API. With each call
/// mapping to a unique point in the fuzzing data.
///
/// This is important to ensure that the fuzzing engine has the
/// ability to individually control the fuzzing of each trait,
/// maximising code coverage.
