Struct EdgeKey

pub struct EdgeKey { /* private fields */ }

An undirected edge, canonically ordered so both sides collide.

Construction is the only place ordering is decided, which is what stops two call sites from disagreeing about whether (3, 1) and (1, 3) are the same edge.

Implementations

impl EdgeKey

pub fn new(a: u32, b: u32) -> Self

Canonical key for an edge between two corners.

Order-insensitive: new(a, b) == new(b, a).

pub const fn lower(self) -> u32

Lower-numbered endpoint.

pub const fn upper(self) -> u32

Higher-numbered endpoint.

pub const fn endpoints(self) -> (u32, u32)

Both endpoints, lower first.

Trait Implementations

impl Clone for EdgeKey

fn clone(&self) -> EdgeKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeKey

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

Formats the value using the given formatter.

impl Hash for EdgeKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for EdgeKey

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EdgeKey

fn eq(&self, other: &EdgeKey) -> 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 PartialOrd for EdgeKey

fn partial_cmp(&self, other: &EdgeKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
