Struct Dart 

Source 
#[repr(C)]
pub struct Dart {
    pub beta1: u32,
    pub beta2: u32,
    pub face: u32,
    pub origin: u32,
}
Expand description

One dart of a 2-map. Field-for-field identical to HalfEdge (renamed): beta1 == next, beta2 == twin, face == face, origin == origin.

16 bytes, #[repr(C)], Pod/Zeroable so it can be bytemuck::cast_sliced alongside HalfEdge buffers where ABI-compatible.

Fields§

§beta1: u32

Next dart in the same face (β₁ permutation). == HalfEdge::next.

§beta2: u32

Twin dart (β₂ involution). INVALID_INDEX for boundary darts. == HalfEdge::twin.

§face: u32

Face this dart belongs to. == HalfEdge::face.

§origin: u32

Origin vertex of this dart. == HalfEdge::origin.
