Struct RotateValue 

pub struct RotateValue {
    pub radians: f64,
    pub velocity: f64,
    pub start_anchor: (f64, f64),
    pub start_location: (f64, f64),
    pub time: f64,
}

A RotateGesture.Value.

The same layout as MagnifyValue with rotation/velocity as Angle, which stores radians and nothing else.

Fields

radians: f64

How far it has turned, in radians. Angle stores radians; the degrees are computed, so the conversion is here rather than through an accessor.

velocity: f64

How fast it is turning, in radians per second.

start_anchor: (f64, f64)

Where the rotation is centred, in unit space.

start_location: (f64, f64)

Where it began, in the gesture’s coordinate space.

time: f64

Seconds since Apple’s reference date.

Implementations

impl RotateValue

pub fn degrees(&self) -> f64

The rotation in degrees, which is what Angle.degrees reports.
