Corrade::Utility::String::ParseResult class new in Git master

#include <Corrade/Utility/String.h>

String parse result.

Stores a ParseState and an optional byte index of where a parsing failure happened, returned from parseDecimal() and parseHexadecimal(). The instance is implicitly convertible to a ParseState, allowing you to use just the enum if details about parsing failure aren't needed for anything:

std::int32_t value;
if(Utility::String::parseDecimal(…, value) !=
   Utility::String::ParseState::Failed)
{
    …
}

Function documentation
