Struct MaterialComparison 

pub struct MaterialComparison {
    pub axes: Vec<String>,
}

Compare materials using performance indices and radar chart data.

Fields

axes: Vec<String>

Property keys used for comparison.

Implementations

impl MaterialComparison

pub fn new(axes: Vec<String>) -> Self

Create a MaterialComparison for the given set of property axes.

pub fn performance_index( &self, record: &MaterialRecord, numerator: &str, denominator: &str, ) -> Option<f64>

Compute a performance index for a record.

The index is the ratio of two properties: numerator / denominator. Returns None if either property is missing or denominator is zero.

pub fn rank_by_index<'a>( &self, records: &[&'a MaterialRecord], numerator: &str, denominator: &str, ) -> Vec<(&'a MaterialRecord, f64)>

Rank materials by performance index (descending, highest first).

pub fn radar_data( &self, record: &MaterialRecord, reference_values: &[f64], ) -> Vec<f64>

Produce radar chart data for a single material: normalized values on each axis.

Each value is divided by reference_values[i] for normalization.

Trait Implementations

impl Debug for MaterialComparison

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

Formats the value using the given formatter.
