Struct Stats

pub struct Stats { /* private fields */ }

The ABC metric.

The ABC metric measures the size of a source code by counting the number of Assignments (A), Branches (B) and Conditions (C). The metric defines an ABC score as a vector of three elements (<A,B,C>). The ABC score can be represented by its individual components (A, B and C) or by the magnitude of the vector (|<A,B,C>| = sqrt(A^2 + B^2 + C^2)).

Implementations

impl Stats

pub fn merge(&mut self, other: &Stats)

Merges a second Abc metric into the first one.

pub fn assignments(&self) -> f64

Returns the Abc assignments metric value.

pub fn assignments_sum(&self) -> f64

Returns the Abc assignments sum metric value.

pub fn assignments_average(&self) -> f64

Returns the Abc assignments average value.

This value is computed dividing the Abc assignments value for the number of spaces.

pub fn assignments_min(&self) -> f64

Returns the Abc assignments minimum value.

pub fn assignments_max(&self) -> f64

Returns the Abc assignments maximum value.

pub fn branches(&self) -> f64

Returns the Abc branches metric value.

pub fn branches_sum(&self) -> f64

Returns the Abc branches sum metric value.

pub fn branches_average(&self) -> f64

Returns the Abc branches average value.

This value is computed dividing the Abc branches value for the number of spaces.

pub fn branches_min(&self) -> f64

Returns the Abc branches minimum value.

pub fn branches_max(&self) -> f64

Returns the Abc branches maximum value.

pub fn conditions(&self) -> f64

Returns the Abc conditions metric value.

pub fn conditions_sum(&self) -> f64

Returns the Abc conditions sum metric value.

pub fn conditions_average(&self) -> f64

Returns the Abc conditions average value.

This value is computed dividing the Abc conditions value for the number of spaces.

pub fn conditions_min(&self) -> f64

Returns the Abc conditions minimum value.

pub fn conditions_max(&self) -> f64

Returns the Abc conditions maximum value.

pub fn magnitude(&self) -> f64

Returns the Abc magnitude metric value.

pub fn magnitude_sum(&self) -> f64

Returns the Abc magnitude sum metric value.
