Macro data_marker 

macro_rules! data_marker {
    ($(#[$doc:meta])* $name:ident, $($debug:literal,)? $struct:ty $(, $(#[$meta:meta])* $info_field:ident = $info_val:expr)* $(,)?) => { ... };
}

Creates a data marker.

Examples

icu_provider::data_marker!(DummyV1, &'static str);

The identifier needs to end with a V followed by one or more digits (the version number).

Invalid identifiers are compile-time errors (as data_marker! uses const).

icu_provider::data_marker!(Dummy, &'static str);
