Struct DebugOverlay 

pub struct DebugOverlay {
    pub item_bounds: bool,
    pub content_bounds: bool,
    pub viewport: bool,
    pub selection_bounds: bool,
}

Visual debug overlays painted on top of normal scene rendering.

Every flag defaults to false. Use this to verify that culling / hit-test / spatial-index / dragging are doing what you expect while developing a scene-based feature; turn off before shipping.

Each flag adds a thin overlay paint with a distinct color so multiple flags can be combined without visual confusion:

• item_bounds: green outline around every visible scene item’s bounds_in_scene.
• content_bounds: blue outline around the scene’s overall content extent (the union of all item bounds).
• viewport: red outline around the visible scene region (the cull rect — the inverse-projected viewport).
• selection_bounds: orange outline around every currently-selected item.

Fields

item_bounds: bool

content_bounds: bool

viewport: bool

selection_bounds: bool

Implementations

impl DebugOverlay

pub const ALL: DebugOverlay

All overlays enabled. Useful to catch any anomaly visually.

pub fn is_active(&self) -> bool

Whether at least one debug overlay is enabled.

Performs copy-assignment from source.

impl Copy for DebugOverlay

impl Debug for DebugOverlay

fn fmt(&self, f: &mut Formatter<'_>) -> Result
