Struct Adjacency 

#[non_exhaustive]
pub struct Adjacency {
    pub face_edges: Vec<u32>,
    pub edge_faces: Vec<[u32; 2]>,
    pub vertex_edge_offsets: Vec<u32>,
    pub vertex_edges: Vec<u32>,
    pub vertex_face_offsets: Vec<u32>,
    pub vertex_faces: Vec<u32>,
    pub edge_is_boundary: Vec<bool>,
    pub vertex_is_boundary: Vec<bool>,
}

Pre-built adjacency arrays in CSR format.

Produced by refinement and consumed by adapter-side mesh construction to avoid redundant topology analysis.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

face_edges: Vec<u32>

Per face-corner → edge index (same layout as face_vertex_indices).

edge_faces: Vec<[u32; 2]>

Two incident faces per edge. u32::MAX = boundary.

vertex_edge_offsets: Vec<u32>

CSR vertex → edge adjacency: per-vertex start offsets into vertex_edges.

vertex_edges: Vec<u32>

Flattened incident-edge indices (sliced by vertex_edge_offsets).

vertex_face_offsets: Vec<u32>

CSR vertex → face adjacency: per-vertex start offsets into vertex_faces.

vertex_faces: Vec<u32>

Flattened incident-face indices (sliced by vertex_face_offsets).

edge_is_boundary: Vec<bool>

Per-edge boundary flag.

vertex_is_boundary: Vec<bool>

Per-vertex boundary flag.

Trait Implementations

impl Clone for Adjacency

fn clone(&self) -> Adjacency

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Adjacency

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Adjacency

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Adjacency

fn eq(&self, other: &Adjacency) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Adjacency

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Adjacency
