### Checking value type
When you don't know the exact type of toml-value, you can get `enum` type from `toml::value`.
You can check what type of value does `toml::value` contains by `is_*` function.
```cpp
toml::value v = /* ... */;
if(v.is_integer() && toml::get<int>(v) == 42)
{
std::cout << "value is 42" << std::endl;
}
```
The complete list of the functions is below.
- `bool toml::value::is_boolean() const noexcept;`
- `bool toml::value::is_integer() const noexcept;`
- `bool toml::value::is_float() const noexcept;`
- `bool toml::value::is_string() const noexcept;`
- `bool toml::value::is_offset_datetime() const noexcept;`
- `bool toml::value::is_local_datetime() const noexcept;`
- `bool toml::value::is_local_date() const noexcept;`
- `bool toml::value::is_local_time() const noexcept;`
- `bool toml::value::is_array() const noexcept;`
- `bool toml::value::is_table() const noexcept;`
- `bool toml::value::is_uninitialized() const noexcept;`
Also, you can get `enum class` value from `toml::value`.
```cpp
switch(data.at("something").type())
@@ -400,6 +424,16 @@ switch(data.at("something").type())
}
```
The complete list of the `enum`s can be found in the section
[underlying types](#underlying-types).
The `enum`s can be used as a parameter of `toml::value::is` function like the following.
```cpp
toml::value v = /* ... */;
if(v.is(toml::value_t::Boolean)) // ...
```
### Fill only the matched value
The more sophisticated way is using `toml::from_toml` and `std::tie`.
