Struct MethodMetrics 

pub struct MethodMetrics { /* private fields */ }

Metrics collected for a single method in a type.

The lint driver populates this struct from HIR analysis. The CC value is the SonarSource-style cognitive complexity count; LOC is the span line count. Both values are pre-computed by the caller.

Examples

use whitaker_common::brain_type_metrics::MethodMetrics;

let m = MethodMetrics::new("parse", 31, 140);
assert_eq!(m.name(), "parse");
assert_eq!(m.cognitive_complexity(), 31);
assert_eq!(m.lines_of_code(), 140);

Implementations

impl MethodMetrics

pub fn new( name: impl Into<String>, cognitive_complexity: usize, lines_of_code: usize, ) -> Self

Creates a new per-method metrics record.

Examples

use whitaker_common::brain_type_metrics::MethodMetrics;

let m = MethodMetrics::new("validate", 10, 45);
assert_eq!(m.name(), "validate");

pub fn name(&self) -> &str

Returns the method name.

pub fn cognitive_complexity(&self) -> usize

Returns the cognitive complexity (CC) value.

pub fn lines_of_code(&self) -> usize

Returns the lines of code (LOC) count.

pub fn is_brain_method(&self, cc_threshold: usize, loc_threshold: usize) -> bool

Returns true when this method qualifies as a “brain method”.

A brain method has cognitive complexity >= cc_threshold and lines of code >= loc_threshold. Both conditions must hold.

Examples

use whitaker_common::brain_type_metrics::MethodMetrics;

let m = MethodMetrics::new("parse", 30, 100);
assert!(m.is_brain_method(25, 80));
assert!(!m.is_brain_method(25, 200));

Trait Implementations

impl Clone for MethodMetrics

fn clone(&self) -> MethodMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MethodMetrics

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

Formats the value using the given formatter.

impl PartialEq for MethodMetrics

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