Struct bevy_internal::utils::FloatOrd

pub struct FloatOrd(pub f32);

A wrapper for floats that implements Ord, Eq, and Hash traits.

This is a work around for the fact that the IEEE 754-2008 standard, implemented by Rust’s f32 type, doesn’t define an ordering for NaN, and NaN is not considered equal to any other NaN.

Wrapping a float with FloatOrd breaks conformance with the standard by sorting NaN as less than all other numbers and equal to any other NaN.

Trait Implementations

impl Clone for FloatOrd

fn clone(&self) -> FloatOrd

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FloatOrd

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

Formats the value using the given formatter.

impl Hash for FloatOrd

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

where H: Hasher,

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 Neg for FloatOrd

type Output = FloatOrd

The resulting type after applying the - operator.

fn neg(self) -> <FloatOrd as Neg>::Output

Performs the unary - operation.

impl Ord for FloatOrd

fn cmp(&self, other: &FloatOrd) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FloatOrd

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

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

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 PartialOrd for FloatOrd

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

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

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

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

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

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

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

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

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

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

impl Copy for FloatOrd

impl Eq for FloatOrd
