Struct PreviewState

pub struct PreviewState {
    pub texture: Option<TextureHandle>,
    drag: Option<(f64, f64, Vec2)>,
    tool_drag: Option<ToolDrag>,
    poly: Vec<(f32, f32)>,
    point_drag: Option<usize>,
    moved_at: Option<Instant>,
    transport: Rect,
}

Fields

texture: Option<TextureHandle>

drag: Option<(f64, f64, Vec2)>

Active overlay drag: clip (x, y) at drag start and the accumulated pointer delta (points).

tool_drag: Option<ToolDrag>

Active tool drag (shape / draw / mask).

poly: Vec<(f32, f32)>

Polygon tool: vertices placed so far, project px relative to the canvas centre.

point_drag: Option<usize>

Select tool: index of the polygon vertex being dragged.

moved_at: Option<Instant>

Last pointer movement (fullscreen hides the cursor after 2 s of stillness).

transport: Rect

Content rect of the transport row last frame — it is centred against the panel using its own measured width, so the first frame is left-aligned and every later one is centred.

impl Default for PreviewState

fn default() -> Self

Returns the “default value” for a type.
