 ## API
 
 The API is offered in two languages, C++ and C. Detailed information can be found in the

 Many parts of the C++ API follow a functional programming approach which is less error-prone. This requires using
 the monadic types `cxx::expected` and `cxx::optional` which are introduced

 With the C++ API, we distinguish between the `typed API` and the `untyped API`. In the typed API, the underlying
 data type is made apparent by typed pointers or references to some data type T (often a template parameter). This allows
