Derive Macro bevy::ecs::prelude::RunCriteriaLabel

#[derive(RunCriteriaLabel)]
{
    // Attributes available to this derive:
    #[run_criteria_label]
}

Generates an impl of the RunCriteriaLabel trait.

This works only for unit structs, or enums with only unit variants. You may force a struct or variant to behave as if it were fieldless with #[run_criteria_label(ignore_fields)].
