Struct EuvDrag 

Source 
pub struct EuvDrag {
    pub x: f64,
    pub y: f64,
    pub delta_x: f64,
    pub delta_y: f64,
    pub travel: f64,
}
Expand description

A single-finger drag described by the current position and the movement accumulated since the drag started.

Fields§

§x: f64

Current X in client coordinates.

§y: f64

Current Y in client coordinates.

§delta_x: f64

X displacement since the drag started.

§delta_y: f64

Y displacement since the drag started.

§travel: f64

Total path length in CSS pixels, not the straight-line distance.

A finger that traces a loop has a large path length and zero delta, which is how a drag is told apart from a tap that wandered slightly.
