Vertex adjacency entry

Size: 8 bytes, aligned for efficient access

Fields

degree: u8

Degree (number of active neighbors)

Component ID (for connectivity tracking)

first_edge_idx: u16

First edge index in adjacency list

_reserved: u16

Reserved for alignment

Implementations

impl VertexEntry

pub const FLAG_ACTIVE: u8 = 1u8

Vertex is active

pub const FLAG_BOUNDARY: u8 = 2u8

Vertex is on cut boundary

pub const FLAG_SIDE: u8 = 4u8

Vertex side in partition (0 or 1)

pub const FLAG_GHOST: u8 = 8u8

Vertex is a ghost (owned by another tile)

pub const fn new() -> Self

Create a new active vertex

pub const fn is_active(&self) -> bool

Check if vertex is active

OPTIMIZATION: #[inline(always)] - called in every vertex iteration

pub const fn side(&self) -> u8

Get partition side (0 or 1)

OPTIMIZATION: Branchless version using bit manipulation

pub fn set_side(&mut self, side: u8)

Set partition side

OPTIMIZATION: Branchless flag update
