Struct LcomInput

#[non_exhaustive]
pub struct LcomInput { /* private fields */ }

Immutable method/field incidence data used by every LCOM formula.

Implementations

impl LcomInput

pub fn new(fields: Vec<String>, method_field_accesses: Vec<Vec<String>>) -> Self

Creates a formula input from declared fields and one accessed-field list per method.

Duplicate field names and duplicate accesses are removed. Accesses to undeclared fields are ignored so every formula uses one consistent method/field incidence relation.

pub fn from_type_info(type_info: &TypeInfo) -> Option<Self>

Builds an input for an eligible Rust metrics type.

Only structs with at least one unambiguously associated inherent method are eligible. Trait impl methods are intentionally absent from the resulting method population.

pub fn field_count(&self) -> usize

Returns the number of declared fields.

pub fn method_count(&self) -> usize

Returns the number of inherent methods represented by the input.

pub fn field_access_count(&self) -> usize

Returns the number of distinct method-to-declared-field accesses.

Trait Implementations

impl Clone for LcomInput

fn clone(&self) -> LcomInput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LcomInput

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

Formats the value using the given formatter.

impl PartialEq for LcomInput

fn eq(&self, other: &LcomInput) -> 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.
