Struct LocalId 

pub struct LocalId<A, Width> { /* private fields */ }

A dense local handle: an axis-branded index value.

Every layout crate aliases this for its node/edge/vertex/hyperedge/incidence identities so a built graph and its borrowed snapshot view yield the same handle type. The Axis brand is a zero-sized PhantomData<fn() -> A> so the handle stays Copy, Send, and Sync regardless of the marker, and satisfies the TopologyId blanket bound when Width does.

Performance

Copy, compare, order, hash, and debug-format are O(1).

Implementations

impl<A, Width> LocalId<A, Width>

pub const fn new(value: Width) -> Self

Wraps a raw index value as an axis-branded handle.

Performance

This function is O(1).

impl<A, Width: Copy> LocalId<A, Width>

pub const fn get(self) -> Width

Returns the raw index value of this handle.

Performance

This function is O(1).

impl<A, Width: Ord> Ord for LocalId<A, Width>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn eq(&self, other: &Self) -> 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.
