Detailed Description

a class convertible to many values used as invalid result.

This class has been designed to make the MANTA_TRY* macros compatible with any function/methods respecting the guideline of error handling.

Internally, these macros can return an object of the InvalidResult type when an error is detected, which will be automatically converted to the return type of the current function/method.

The documentation for this struct was generated from the following files:
