Struct Datetime

struct Datetime { ... }

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.

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).

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- specific.

ldt1 = 1979-05-27T07:32:00
ldt2 = 1979-05-27T00:32:00.999999

3. Local Date: If only date is given, Datetime corresponds to a Local Date; see the docs for Date.

4. Local Time: If only time is given, Datetime corresponds to a Local Time; see the docs for Time.
