Struct ViewportZoomRequest 

pub struct ViewportZoomRequest {
    pub anchor_screen: CanvasPoint,
    pub target_zoom: f32,
    pub min_zoom: f32,
    pub max_zoom: f32,
}

Renderer-neutral zoom request anchored at a logical screen-pixel point.

Fields

anchor_screen: CanvasPoint

Logical screen-pixel point that should keep the same canvas coordinate while zooming.

target_zoom: f32

Desired zoom before clamping.

min_zoom: f32

Inclusive minimum zoom clamp.

max_zoom: f32

Inclusive maximum zoom clamp.

fn eq(&self, other: &ViewportZoomRequest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
