impl MzReflect for CastUint16ToNumeric

fn add_to_reflected_type_info(rti: &mut ReflectedTypeInfo)

Adds names and types of the fields of the struct or enum to rti.

impl Ord for CastUint16ToNumeric

fn cmp(&self, other: &CastUint16ToNumeric) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
