Struct SameKey 

pub struct SameKey(pub Shape);

A key that hashes and compares by Shape::is_same: node and placement, ignoring orientation.

Wrapping rather than offering a custom hasher, because the danger being guarded against is a map whose comparison and hash disagree: a set keyed on “same” semantics but hashing the orientation as well will silently hold both an edge and its reverse. Making the equivalence part of the type means the two can never drift apart.

Trait Implementations

impl Clone for SameKey

fn clone(&self) -> SameKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SameKey

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

Formats the value using the given formatter.

impl Eq for SameKey

impl Hash for SameKey

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 PartialEq for SameKey

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.
