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

fn le(&self, other: &AltNeu<T>) -> bool

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

fn gt(&self, other: &AltNeu<T>) -> bool

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

fn ge(&self, other: &AltNeu<T>) -> bool

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

impl<T: PartialEq> PartialEq<AltNeu<T>> for AltNeu<T>

fn eq(&self, other: &AltNeu<T>) -> bool

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

fn ne(&self, other: &AltNeu<T>) -> bool

This method tests for !=.

impl<T: Default> Default for AltNeu<T>

fn default() -> AltNeu<T>

Returns the "default value" for a type.

impl<T: Clone> Clone for AltNeu<T>

fn clone(&self) -> AltNeu<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Ord> Ord for AltNeu<T>

fn cmp(&self, other: &AltNeu<T>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.

    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl<T: Timestamp> Refines<T> for AltNeu<T>
