Struct Emphasis 

pub struct Emphasis {
    pub selected_solids: HashSet<String>,
    pub selected_faces: HashSet<String>,
    pub selected_edges: HashSet<String>,
    pub selected_vertices: Vec<VertexRef>,
    pub selected_datums: HashSet<String>,
    pub hovered_solids: HashSet<String>,
    pub hovered_faces: HashSet<String>,
    pub hovered_edges: HashSet<String>,
    pub hovered_vertices: Vec<VertexRef>,
    pub hovered_datums: HashSet<String>,
    pub generation: u64,
}

The emphasis state (selection + hover), name-keyed like SelectionFilter. Solid-level emphasis cascades to that solid’s faces/edges (the SelectionState._applyToSolid behavior).

Fields

selected_solids: HashSet<String>

selected_faces: HashSet<String>

selected_edges: HashSet<String>

selected_vertices: Vec<VertexRef>

selected_datums: HashSet<String>

Selected construction datum/plane FRAMES, keyed by frame NAME ({id}:XY for a DATUM base plane, {id} for a PLANE feature). Datums carry no resident geometry, so — like the render-color feed — they emphasize purely by name; a selected datum is re-colored with the selection accent when the engine re-feeds the datum planes.

hovered_solids: HashSet<String>

hovered_faces: HashSet<String>

hovered_edges: HashSet<String>

hovered_vertices: Vec<VertexRef>

hovered_datums: HashSet<String>

HOVERED construction datum/plane FRAMES — the hover twin of selected_datums, keyed the same way. Construction planes are ordinary pick candidates, so the pointer (and a pick-list row) pre-highlights one exactly like a face; the accent is applied when the engine re-feeds the datum planes.

generation: u64

Bumped on every change — cache key for derived GPU state.

Implementations

impl Emphasis

pub fn is_empty(&self) -> bool

pub fn apply_json(&mut self, json: &str) -> Result<(), String>

Replace the whole emphasis state from the R3 JSON shape: {selected: {solids, faces, edges, vertices:[{solid,position}]}, hovered: {...}}.

impl Emphasis

pub fn face_state(&self, solid: &str, face: &str) -> EmphasisState

pub fn edge_state(&self, solid: &str, edge: &str) -> EmphasisState

pub fn vertex_state( &self, solid: &str, position: [f64; 3], tol: f64, ) -> EmphasisState

Trait Implementations

impl Debug for Emphasis

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

Formats the value using the given formatter.

impl Default for Emphasis

fn default() -> Emphasis

Returns the “default value” for a type.
