8/// AWS S3 [region identifier](https://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region),
9/// passing in custom values is also possible, in that case it is up to you to pass a valid endpoint,
10/// otherwise boom will happen :)
11///
12/// Serde support available with the `serde` feature
13///
14/// # Example
15/// ```
16/// use std::str::FromStr;
17/// use awsregion::Region;
18///
19/// // Parse from a string
20/// let region: Region = "us-east-1".parse().unwrap();
21///
22/// // Choose region directly
23/// let region = Region::EuWest2;
24///
25/// // Custom region requires valid region name and endpoint
26/// let region_name = "nl-ams".to_string();
27/// let endpoint = "https://s3.nl-ams.scw.cloud".to_string();
28/// let region = Region::Custom { region: region_name, endpoint };
