Function iso3166_1::num_range

pub fn num_range<'a>(
    from: Option<&str>, 
    to: Option<&str>
) -> Vec<CountryCode<'a>>

Returns a Vec of CountryCodes that have a numeric value within the range of the from and to given. The from and to are optional, and can either be None or Some(&str) for variations of the range wanted.

Examples

Getting all values between 100 and 300:

let countries = iso3166_1::num_range(Some("100"), Some("300"));

Getting all values from 400 and beyond:

let countries = iso3166_1::num_range(Some("400"), None);

Getting all values up to 500:

let countries = iso3166_1::num_range(None, Some("500"));

Getting no values, if that's your thing:

let countries = iso3166_1::num_range(None, None);
