StringConv< X, COND > Struct Template Reference

#include "lib/meta/util.hpp"

Description

template<typename X, typename COND = void>
struct util::StringConv< X, COND >

failsafe invocation of custom string conversion.

Returns

string to represent the object, by default a type display

Remarks

this is a lightweight solution to at least get any human readable string representation for pretty much every language object. This minimal solution is defined here, to allow for built-in diagnostics for custom types without the danger of creating much header inclusion and code size bloat. A more elaborate, extended solution, including lexical conversions for numbers, is defined in format-obj.hpp

Template Parameters

X	the nominal type to base the string conversion on; should be a plain type (class or value) without CV-qualification and references

Note

any exceptions during string conversion are caught and silently ignored; the returned string indicates "↯" in this case.
