Enum LcomMetric

#[non_exhaustive]
pub enum LcomMetric {
    Lcom96a,
    Lcom96b,
    Lcom1,
    Lcom2,
    Lcom3,
    Lcom4,
    Lcom5,
    LcomStar,
}

One formula in the lack-of-cohesion-of-methods family.

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.

Lcom96a

Henderson-Sellers normalized method/field distance, 1996a spelling.

Lcom96b

Henderson-Sellers method/field density complement, 1996b spelling.

Lcom1

Difference between non-sharing and sharing method-pair counts.

Lcom2

Method/field density complement.

Lcom3

Normalized method/field distance.

Lcom4

Connected components in the shared-field method graph.

Lcom5

Henderson-Sellers normalized method/field distance.

LcomStar

LCOM-star normalized method/field distance.

Implementations

impl LcomMetric

pub const ALL: [Self; 8]

Every LCOM metric in stable display order.

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

Returns the stable public metric name.

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

Returns the formula’s stable description.

pub fn calculate(self, input: &LcomInput) -> f64

Calculates this formula over a prepared method/field incidence relation.

Zero methods produce zero for every formula. One method produces one only for LCOM4 and zero otherwise. With multiple methods and no fields, normalized/density formulas produce zero, while LCOM1 and LCOM4 retain their method-pair and component meanings.

Trait Implementations

impl Clone for LcomMetric

fn clone(&self) -> LcomMetric

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LcomMetric

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

Formats the value using the given formatter.

impl Display for LcomMetric

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

Formats the value using the given formatter.

impl Hash for LcomMetric

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 LcomMetric

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

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

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