Enum rustc_apfloat::ieee::Loss

enum Loss {
    ExactlyZero,
    LessThanHalf,
    ExactlyHalf,
    MoreThanHalf,
}

Enum that represents what fraction of the LSB truncated bits of an fp number represent.

This essentially combines the roles of guard and sticky bits.

Variants

ExactlyZero

LessThanHalf

ExactlyHalf

MoreThanHalf

Implementations

impl Loss

fn combine(self, less_significant: Loss) -> Loss

Combine the effect of two lost fractions.

fn through_truncation(limbs: &[u128], bits: usize) -> Loss

Returns the fraction lost were a bignum truncated losing the least significant bits bits.

Trait Implementations

impl Clone for Loss

fn clone(&self) -> Loss

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Loss

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

Formats the value using the given formatter.

impl PartialEq<Loss> for Loss

fn eq(&self, other: &Loss) -> 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 Copy for Loss

impl Eq for Loss

impl StructuralEq for Loss

impl StructuralPartialEq for Loss

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
