/// A parsed TOML datetime value
///
/// This structure is intended to represent the datetime primitive type that can
/// be encoded into TOML documents. This type is a parsed version that contains
/// all metadata internally.
///
/// Currently this type is intentionally conservative and only supports
/// `to_string` as an accessor. Over time though it's intended that it'll grow
/// more support!
///
/// Note that if you're using `Deserialize` to deserialize a TOML document, you
/// can use this as a placeholder for where you're expecting a datetime to be
/// specified.
///
/// Also note though that while this type implements `Serialize` and
/// `Deserialize` it's only recommended to use this type with the TOML format,
/// otherwise encoded in other formats it may look a little odd.
///
/// Depending on how the option values are used, this struct will correspond
/// with one of the following four datetimes from the [TOML v1.0.0 spec]:
///
/// | `date` | `time` | `offset` | TOML type |
/// | --------- | --------- | --------- | ------------------ |
/// | `Some(_)` | `Some(_)` | `Some(_)` | [Offset Date-Time] |
/// | `Some(_)` | `Some(_)` | `None` | [Local Date-Time] |
/// | `Some(_)` | `None` | `None` | [Local Date] |
/// | `None` | `Some(_)` | `None` | [Local Time] |
///
/// **1. Offset Date-Time**: If all the optional values are used, `Datetime`
/// corresponds to an [Offset Date-Time]. From the TOML v1.0.0 spec:
///
/// > To unambiguously represent a specific instant in time, you may use an
/// > RFC 3339 formatted date-time with offset.
/// >
/// > ```toml
/// > odt1 = 1979-05-27T07:32:00Z
/// > odt2 = 1979-05-27T00:32:00-07:00
/// > odt3 = 1979-05-27T00:32:00.999999-07:00
/// > ```
/// >
/// > For the sake of readability, you may replace the T delimiter between date
/// > and time with a space character (as permitted by RFC 3339 section 5.6).
/// >
/// > ```toml
/// > odt4 = 1979-05-27 07:32:00Z
/// > ```
///
/// **2. Local Date-Time**: If `date` and `time` are given but `offset` is
/// `None`, `Datetime` corresponds to a [Local Date-Time]. From the spec:
///
/// > If you omit the offset from an RFC 3339 formatted date-time, it will
/// > represent the given date-time without any relation to an offset or
/// > timezone. It cannot be converted to an instant in time without additional
/// > information. Conversion to an instant, if required, is implementation-
