§Example

use icu::properties::CanonicalCombiningClass;

let lookup = CanonicalCombiningClass::name_to_enum_mapper();
// short name for value
assert_eq!(lookup.get_strict("AL"), Some(CanonicalCombiningClass::AboveLeft));
assert_eq!(lookup.get_strict("ATBL"), Some(CanonicalCombiningClass::AttachedBelowLeft));
assert_eq!(lookup.get_strict("CCC10"), Some(CanonicalCombiningClass::CCC10));
// long name for value
assert_eq!(lookup.get_strict("Above_Left"), Some(CanonicalCombiningClass::AboveLeft));
assert_eq!(lookup.get_strict("Attached_Below_Left"), Some(CanonicalCombiningClass::AttachedBelowLeft));
// name has incorrect casing and hyphens
assert_eq!(lookup.get_strict("attached-below-left"), None);
// loose matching of name
assert_eq!(lookup.get_loose("attached-below-left"), Some(CanonicalCombiningClass::AttachedBelowLeft));
// fake property
assert_eq!(lookup.get_strict("Linear_Z"), None);
