Provided Methods§

Source

unsafe fn identifier(mtm: MainThreadMarker) -> Retained<NSString>
where Self: Sized + ClassType,

A unique identifier string for the trait (reverse-DNS format recommended). Allows the trait to be encoded/decoded, and to map both a Swift and Objective-C trait to the same data.

Source

unsafe fn name(mtm: MainThreadMarker) -> Retained<NSString>
where Self: Sized + ClassType,

A short human-readable name for the trait, e.g. for printing and debugging output. By default, the trait’s class name is used when not implemented.

Source

unsafe fn affectsColorAppearance(mtm: MainThreadMarker) -> bool
where Self: Sized + ClassType,

Whether the trait is used to resolve dynamic colors (or images), and changes to the trait should automatically trigger views using dynamic colors/images to update their appearance. Default is NO.
