Struct unic_ucd_age::Age

pub struct Age(_);

Represents values of the Unicode character property Age.

The Age property indicates the age of a character, which is defined based on the first Unicode version in which a particular Unicode character was assigned (as character or noncharacter).

Note: Age type has a reverse ordering compared to UnicodeVersion, because a character is older (has greater age) of another character if, and only if, it has a older (smaller) UnicodeVersion number.

Unicode versions with character assignement always have the Micro (Update) version value of zero (0). Therefore, all UnicodeVersion values return from Age will have their macro field as 0.

The earliest (largest) value for this property is UnicodeVersion { major: 1, minor: 1, micro: 0 }, because of the massive changes for the merger of the Unicode Standard with ISO 10646.

The latest (smallest) value for this property is always equal to or greater than UNICODE_VERSION. (Only not equal when UNICODE_VERSION has non-zero micro value.)
