Struct PlatformViewFrame 

pub struct PlatformViewFrame {
    pub slot_id: u64,
    pub view_type: String,
    pub params_json: String,
    pub params_generation: u64,
    pub rect: Rect,
    pub clip: Option<Rect>,
    pub visible: bool,
    pub interactive: bool,
    pub shields: Vec<Rect>,
}

A platform-view child’s paint-time frame — everything a shell’s native compositor needs to place, size, clip, and dispose a native sibling view for one paint pass.

All rects are logical px, absolute window coordinates — the same space PaintCtx::report_hero callers use, built from the painting pod’s PaintCtx::origin/PaintCtx::size. Frames are paint-pass-scoped: crate::app::RenderRoot::paint replaces the whole collection every pass, so a slot that didn’t paint this pass (a culled subtree) simply has no frame in crate::app::RenderRoot::platform_view_frames — the shell’s differ owns absent-means-hide/dispose semantics, not this crate.

Fields

slot_id: u64

Stable per-widget-instance id, allocated once via next_slot_id at construction — never derived from tree position, so a reorder keeps identity.

view_type: String

"dev.frust.<Factory>" convention naming which native view factory creates this slot’s platform view.

params_json: String

Opaque creation params for the native factory (may be empty).

params_generation: u64

Bumped by the widget whenever params_json changes; this crate only ever carries the number through.

rect: Rect

Absolute paint bounds.

clip: Option<Rect>

visible_rect (see PaintCtx::visible_rect) intersected with rect, or None when fully visible — no scroll ancestor is clipping it.

visible: bool

false ⇒ hidden (offscreen/culled by the widget itself, distinct from simply being absent from the collection this pass).

interactive: bool

Mode B input forwarding: whether the hosted native view should receive pointer input — a touch-DOWN inside rect (and outside every shields rect) hands the whole gesture to the native sibling in the embedding. false (the default) keeps the v1 no-input contract: the frust surface consumes everything.

shields: Vec<Rect>

The z-shield list: absolute-coordinate regions where frust content drawn OVER this slot must keep winning input. Only consulted when interactive. Same coordinate space as rect.

Carries only the slot’s own manually declared shields (PlatformViewView::shield_local, the escape hatch). The ordinary source is auto-collection: a shield(child) wrapper reports its painted rect through PaintCtx::report_input_shield, and the shell-side differ merges whichever of those intersect this rect into the command it emits — so the shipped wire shape is the union of both, assembled one layer up.
