For countries with multiple levels of subdivision (for example, nations within the United Kingdom), this variable gives the more specific subdivision. This field can be `None` for countries that do not have ISO country subdivision codes. For example, `None` is given for IP addresses assigned to the Åland Islands (country code AX, illustrated below). #### Examples Region values are the subdivision part only. For typical use, a subdivision is normally formatted with its associated country code. The following example illustrates constructing an [ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2) two-part country and subdivision code from the respective fields: ```rust let code = if let Some(region) = geo.region() { format!("{}-{}", geo.country_code(), region) } else { format!("{}", geo.country_code()) }; ``` | `code` | Region Name | Country | ISO 3166-2 subdivision | | ---------- | ----------------- | ------------------ | ---------------------- | | `AX` | Ödkarby | Åland Islands | (none) | | `DE-BE` | Berlin | Germany | Land (State) | | `GB-BNH` | Brighton and Hove | United Kingdom | Unitary authority | | `JP-13` | 東京都 (Tōkyō-to) | Japan | Prefecture | | `RU-MOW` | Москва́ (Moscow) | Russian Federation | Federal city | | `SE-AB` | Stockholms län | Sweden | Län (County) | | `US-CA` | California | United States | State | **Parameters** - `self`: `&Self` **Returns** `Option<&str>` ### utc_offset **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/geo.rs#353 ```rust fn utc_offset(&self) -> Option ``` Time zone offset from coordinated universal time (UTC) for `city`. This is represented using the [`UtcOffset`](https://docs.rs/time/latest/time/utc_offset/struct.UtcOffset.html) type from the [`time`](https://docs.rs/time/latest/time/index.html) library. See `time`'s documentation for more details on how to format this type or use it in time calculations. Returns `None` if the geolocation database does not have a time zone offset for this IP address. **Parameters** - `self`: `&Self` **Returns** `Option` ## Trait implementations ### impl Clone for Geo #### clone **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/geo.rs#133 ```rust fn clone(&self) -> Self ``` **Parameters** - `self`: `&Self` **Returns** `Self` ### impl Debug for Geo #### fmt **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/geo.rs#133 ```rust fn fmt(&self, f: &mut Formatter<'_>) -> Result ``` **Parameters** - `self`: `&Self` - `f`: `&mut $crate::fmt::Formatter` **Returns** `$crate::fmt::Result` ## Auto trait implementations - `Freeze` - `RefUnwindSafe` - `Send` - `Sync` - `Unpin` - `UnsafeUnpin` - `UnwindSafe` ## Blanket implementations - `Any` - `Borrow` - `BorrowMut` - `CloneToUninit` - `Downcast` - `DowncastSync` - `ErasedDestructor` - `From` - `Into` - `IntoEither` - `Same` - `ToOwned` - `TryFrom` - `TryInto`
