Enum LogQuality 

#[non_exhaustive]
pub enum LogQuality {
    Excellent,
    Good,
    Acceptable,
    Poor,
    AtSingularity,
}

Quality levels for logarithm computations.

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.

Excellent

Excellent conditioning: κ < 2, full precision expected

Good

Good conditioning: κ < 10, reliable results

Acceptable

Acceptable conditioning: κ < 100, ~2 digits precision loss

Poor

Poor conditioning: κ < 1000, significant precision loss

AtSingularity

At or near singularity, result unreliable

Trait Implementations

impl Clone for LogQuality

fn clone(&self) -> LogQuality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogQuality

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

Formats the value using the given formatter.

impl Display for LogQuality

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

Formats the value using the given formatter.

impl PartialEq for LogQuality

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

impl Eq for LogQuality
