Test_providers.Int_printerInt_printer is a provider for Test_interfaces.Int_printer.
The structure of this file is very similar to the Eio_reader module, thus is not documented in details. Refer to Eio_reader for more info.
We use it as an alternate to Num_printer, which is able to print both integers and floats to demonstrate cases involving sub typing.
