/**
|
||||||
|
* A ResultRange defines an inclusive range of error descriptions within an error module.
|
||||||
|
* This can be used to check whether the description of a given ResultCode falls within the range.
|
||||||
|
* The conversion function returns a ResultCode with its description set to description_start.
|
||||||
|
*
|
||||||
|
* An example of how it could be used:
|
||||||
|
* \code
|
||||||
|
* constexpr ResultRange ResultCommonError{ErrorModule::Common, 0, 9999};
|
||||||
|
*
|
||||||
|
* ResultCode Example(int value) {
|
||||||
|
* const ResultCode result = OtherExample(value);
|
||||||
|
*
|
||||||
|
* // This will only evaluate to true if result.module is ErrorModule::Common and
|
||||||
|
* // result.description is in between 0 and 9999 inclusive.
|
||||||
|
* if (ResultCommonError.Includes(result)) {
|
||||||
|
* // This returns ResultCode{ErrorModule::Common, 0};
|
||||||
|
* return ResultCommonError;
|
||||||
|
* }
|
||||||
|
*
|
||||||
|
* return ResultSuccess;
|
||||||
|
* }
|
||||||
