Enum FitnessClass 

#[repr(u8)]
pub enum FitnessClass {
    Tight = 0,
    Normal = 1,
    Loose = 2,
    VeryLoose = 3,
}

Fitness class for a line based on its adjustment ratio.

The adjustment ratio r = slack / stretch (or slack / shrink for negative slack) determines how much a line differs from its natural width.

Variants

Tight = 0

r < -0.5 (compressed line).

Normal = 1

-0.5 ≤ r < 0.5 (well-set line).

Loose = 2

0.5 ≤ r < 1.0 (somewhat loose line).

VeryLoose = 3

r ≥ 1.0 (very loose line).

Implementations

impl FitnessClass

pub fn from_ratio(ratio: f64) -> Self

Classify a line’s fitness from its adjustment ratio.

The ratio is slack / width for positive slack (stretch) or slack / width for negative slack (shrink).

pub const fn incompatible(self, other: Self) -> bool

Whether two consecutive fitness classes are incompatible (differ by more than one level), warranting a fitness demerit.

Trait Implementations

impl Clone for FitnessClass

fn clone(&self) -> FitnessClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FitnessClass

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

Formats the value using the given formatter.

impl Hash for FitnessClass

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 FitnessClass

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

fn eq(&self, other: &FitnessClass) -> 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 FitnessClass

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