Struct EntityVisibility 

pub struct EntityVisibility { /* private fields */ }

The hidden-entity sets of ONE solid (empty = all visible). Indices are into the owning SolidDisplay’s faces / edges / vertices.

Implementations

impl EntityVisibility

pub fn is_visible(&self, kind: EntityKind, index: usize) -> bool

Whether entity index of kind is currently shown.

pub fn any_hidden(&self, kind: EntityKind) -> bool

Whether ANY entity of kind is hidden — the render pass’s fast-path guard (nothing hidden ⇒ keep the single whole-buffer draw).

pub fn set_visible(&mut self, kind: EntityKind, index: usize, visible: bool)

Show/hide a single entity of kind.

pub fn set_group_visible( &mut self, kind: EntityKind, count: usize, visible: bool, )

Show/hide EVERY entity of kind. count is the number of entities of that kind, so “hide all” enumerates them (and “show all” clears).

pub fn group_state(&self, kind: EntityKind, count: usize) -> GroupState

The group tristate for count entities of kind. O(1): the hidden set satisfies hidden ⊆ 0..count (see all_hidden), so its len() IS the hidden count — no per-entity scan. Called per solid per egui frame by the Scene panel, so the O(1) matters on point/edge-heavy models.

pub fn is_face_visible(&self, index: usize) -> bool

pub fn is_edge_visible(&self, index: usize) -> bool

pub fn is_vertex_visible(&self, index: usize) -> bool

pub fn any_face_hidden(&self) -> bool

pub fn any_edge_hidden(&self) -> bool

pub fn any_vertex_hidden(&self) -> bool

pub fn all_hidden(&self, kind: EntityKind, count: usize) -> bool

Whether EVERY entity of kind is hidden — O(1). A solid’s hidden set is always paired with the entity counts it was built against: geometry changes replace the whole SolidDisplay (fresh, empty visibility), and a reused display keeps its counts AND its hidden set together — so hidden ⊆ 0..count holds universally and len() == count ⇔ the whole group is off (individual hides leave len() < count). >= rather than == is defensive only. The render pass uses this to skip a fully-hidden group’s per-vertex draw loop.

pub fn all_vertices_hidden(&self, count: usize) -> bool
