Struct TouchId 

pub struct TouchId(pub u64);

Identifies one touch (finger or stylus contact) for its lifetime, from TouchPhase::Started through TouchPhase::Ended or TouchPhase::Cancelled.

The value is opaque and platform-defined; it is only guaranteed to be stable for the duration of the touch and unique among concurrent touches.
