Definition for number-like scalar affinities

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

bits: NumberBits

Bit representation of numbers

min: PtrConst<'static>

Minimum representable value

max: PtrConst<'static>

Maximum representable value

positive_infinity: Option<PtrConst<'static>>

Positive infinity representable value

negative_infinity: Option<PtrConst<'static>>

Negative infinity representable value

nan_sample: Option<PtrConst<'static>>

Example NaN (Not a Number) value. Why sample? Because there are many NaN values, and we need to provide a representative one.

positive_zero: Option<PtrConst<'static>>

Positive zero representation. If there’s only one zero, only set this one.

negative_zero: Option<PtrConst<'static>>

Negative zero representation

epsilon: Option<PtrConst<'static>>

“Machine epsilon” (https://en.wikipedia.org/wiki/Machine_epsilon), AKA relative approximation error, if relevant

Implementations

impl NumberAffinity

pub const fn builder() -> NumberAffinityBuilder

Returns a builder for NumberAffinity

Trait Implementations

impl Clone for NumberAffinity

fn clone(&self) -> NumberAffinity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumberAffinity

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

Formats the value using the given formatter.

impl Hash for NumberAffinity

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 PartialEq for NumberAffinity

fn eq(&self, other: &NumberAffinity) -> 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.
