macro_rules! region { ($string:literal) => { ... }; }
Expand description
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");
