bfp uses C++ classes which store the format hyperparameters as fields. If you'd rather a C/C++ library memory layout which reflects the bitwidth of the particular posit:
contains both a julia library and a C/C++ library. Posits are implemented as a C type and a C++ class where the type and class sizes correspond to the bitwidth.
