## Casting value
So far, `toml::get` is introduced, but if you don't need any type conversion,
`as_*` is simpler to use.
```cpp
toml::value v = /* ... */;
if(v.is_integer() && v.as_integer() == 42)
{
std::cout << "value is 42" << std::endl;
}
```
The complete list of the functions is below.
```cpp
const toml::value v(/*...*/);
v.as_boolean();
v.as_integer();
v.as_float();
v.as_string();
v.as_offset_datetime();
v.as_local_datetime();
v.as_local_date();
v.as_local_time();
v.as_array();
v.as_table();
v.as_uninitialized();
