Trait Implementations

impl<S: Clone, P: Clone, O: Clone, G: Clone> Clone for Quad<S, P, O, G>

Feeds this value into the given Hasher.

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

impl<S: Ord, P: Ord, O: Ord, G: Ord> Ord for Quad<S, P, O, G>

fn cmp(&self, other: &Quad<S, P, O, G>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl<S1: PartialEq<S2>, P1: PartialEq<P2>, O1: PartialEq<O2>, G1: PartialEq<G2>, S2, P2, O2, G2> PartialEq<Quad<S2, P2, O2, G2>> for Quad<S1, P1, O1, G1>

fn eq(&self, other: &Quad<S2, P2, O2, G2>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<S1: PartialOrd<S2>, P1: PartialOrd<P2>, O1: PartialOrd<O2>, G1: PartialOrd<G2>, S2, P2, O2, G2> PartialOrd<Quad<S2, P2, O2, G2>> for Quad<S1, P1, O1, G1>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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