fn clone( &self, ) -> GenericGradient<LineDirection, LengthPercentage, NonNegativeLength, NonNegativeLengthPercentage, Position, Angle, AngleOrPercentage, Color>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<LineDirection: Debug, LengthPercentage: Debug, NonNegativeLength: Debug, NonNegativeLengthPercentage: Debug, Position: Debug, Angle: Debug, AngleOrPercentage: Debug, Color: Debug> Debug for GenericGradient<LineDirection, LengthPercentage, NonNegativeLength, NonNegativeLengthPercentage, Position, Angle, AngleOrPercentage, Color>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
