Macro icu_locid::subtags_variant

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

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

Examples

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

assert_eq!(
  icu_locid::subtags_variant!("posix"),
  "posix".parse::<icu_locid::subtags :: Variant>().unwrap()
);

Invalid input is a compile failure:

icu_locid::subtags_variant!("yes");

Variant: crate::subtags :: Variant
