Struct RoundingMode

pub struct RoundingMode(/* private fields */);

Available on AArch64 only.

Floating-point rounding mode, as defined by IEEE 754.

Implementations

impl RoundingMode

pub const Nearest: Self

Round to the nearest number, with ties toward even numbers.

pub const PlusInfinity: Self

Round toward positive infinity.

pub const MinusInfinity: Self

Round toward negative infinity.

pub const Zero: Self

Round toward zero (truncate).

pub const fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

An identical method is available through the CEnum trait, but this version is declared const (which is currently unstable on traits).

Trait Implementations

impl CEnum<u8> for RoundingMode

fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

impl Clone for RoundingMode

fn clone(&self) -> RoundingMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RoundingMode

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

Formats the value using the given formatter.

impl Default for RoundingMode

fn default() -> RoundingMode

Returns the “default value” for a type.

impl From<RoundingMode> for u8

fn from(enum_value: RoundingMode) -> Self

Converts to this type from the input type.

impl From<u8> for RoundingMode

fn from(repr: u8) -> Self

Converts to this type from the input type.

impl Hash for RoundingMode

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 RoundingMode

fn cmp(&self, other: &RoundingMode) -> 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.

impl PartialEq for RoundingMode

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

impl PartialOrd for RoundingMode

fn partial_cmp(&self, other: &RoundingMode) -> 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.
