This library support single_include,so you need only include "any.hpp".
This is a simple example:
#include<iostream>
#include"any.hpp"
struct Student{
Student(int id,const char* name):id_(id),name_(name){}
int id_;
const char* name_;
};
int main(){
nonstd::any t = "hello world";
t = 324; //changed to int
t = 3.4353; //changed to double
t = Student{32,"bob"}; //changed to custom type
t.emplace<Student>(32,"bob"); //the same to previous,but it can avoid copy
auto name =t.type().name(); //get typename from std::typeinfo method
t.has_value(); //to judge value exist
auto v = nonstd::any_cast<Student>(t); //get value from any
std::cout<<"typename:"<<name<<" Student name:" <<v.name_;
}
