Macro icu_locid::subtags_region

macro_rules! subtags_region {
    ($string:literal) => { ... };
}

A macro allowing for compile-time construction of valid Region subtags.

Examples

Parsing errors don’t have to be handled at runtime:

assert_eq!(
  icu_locid::subtags_region!("FR"),
  "FR".parse::<icu_locid::subtags :: Region>().unwrap()
);

Invalid input is a compile failure:

icu_locid::subtags_region!("12");

Region: crate::subtags :: Region
