Enum RoundingMode 

#[non_exhaustive]
pub enum RoundingMode {
    Rne,
    Rna,
    Rtp,
    Rtn,
    Rtz,
}

A rounding direction (IEEE 754 §4.3), named as in SMT-LIB.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Rne

To nearest, ties to even (the default everywhere).

Rna

To nearest, ties away from zero.

Rtp

Toward +∞.

Rtn

Toward −∞.

Rtz

Toward zero.

Implementations

impl RoundingMode

pub const ALL: [RoundingMode; 5]

Every mode.

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

The name in the text syntax: "rne", "rna", "rtp", "rtn", "rtz".

pub fn from_name(name: &str) -> Option<RoundingMode>

The mode with this name.

Trait Implementations

impl Clone for RoundingMode

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

Performs copy-assignment from source.

impl Copy for RoundingMode

impl Debug for RoundingMode

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

impl Eq for RoundingMode

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)

impl Ord for RoundingMode

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for RoundingMode

fn partial_cmp(&self, other: &Self) -> 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
