from.hpp

# from.hpp #

Defines a `struct` used for conversion from `toml::value` in `toml::get` and `toml::find`.

You can achieve the same functionality by adding a `from_toml` member function, but for classes where you cannot add member functions, use `from<T>`.

This file does not provide specific implementations. Please specialize this `struct` when using.

    namespace toml
    {

    template<typename T>
    struct from;

    } // toml

## Example #

    namespace extlib
    {
    struct foo
    {
        int a;
        std::string b;
    };
    } // extlib

    #include <toml11/from.hpp>

    namespace toml
    {
    template<>
    struct from<extlib::foo>
    {
        template<typename TC>
        static extlib::foo from_toml(const toml::basic_value<TC>& v)
        {
            return extlib::foo{toml::find<int>(v, "a"), toml::find<std::string>(v, "b")};
        }
    };
    } // toml
