impl Ord for Kind

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Kind> for Kind

pub fn eq(&self, other: &Kind) -> bool

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

pub fn ne(&self, other: &Kind) -> bool

This method tests for !=.

impl PartialOrd<Kind> for Kind

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

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

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

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

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

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

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

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

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