Enum FloatKind 

pub enum FloatKind {
    Float,
    Double,
    LongDouble,
}

The real floating types.

The decimal floating types from C23 are deferred past 1.0 by spec/19-open-questions.md and are deliberately absent rather than present and unimplemented.

Variants

Float

float, always the binary32 format.

Double

double, always the binary64 format.

LongDouble

long double, whose format is a target property and is not always distinct from double. It is 80 bits of x87 on SysV x86-64, quad precision on AArch64 Linux, and the same as double on Apple and Windows.

Implementations

impl FloatKind

pub const ALL: [FloatKind; 3]

Every real floating type, in rank order.

pub const fn rank(self) -> u8

The conversion rank, which for floating types is just the ordering.

pub const fn as_str(self) -> &'static str

How the type is spelled in a diagnostic.

Trait Implementations

impl Clone for FloatKind

fn clone(&self) -> FloatKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FloatKind

impl Debug for FloatKind

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

Formats the value using the given formatter.

impl Eq for FloatKind

impl Hash for FloatKind

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

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 Ord for FloatKind

fn cmp(&self, other: &FloatKind) -> 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,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for FloatKind

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FloatKind

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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