Detailed Description

template<typename... functors>
struct bio::meta::overloaded< functors >

Wrapper to create an overload set of multiple functors.

Template Parameters

functors

The types of the functors (usually deduced).

This helper allows creating a function object that statically dispatches between other function objects (usually provided via lambda expressions).

Example

#include <string>
#include <fmt/core.h>
#include <bio/meta/overloaded.hpp>
 
int main()
{
    bio::meta::overloaded fn{
      [] (std::string const & s)      { fmt::print("I am a string:{}\n", s); },
      [] (std::integral auto const i) { fmt::print("I am an int:  {}\n", i); }
    };
 
    fn("foobar"); // picks first "overload"
    fn(3);        // picks second "overload"
}
