Struct Preference 

pub struct Preference<F>
where
    F: Fn(&[f64]) -> f64,
{ /* private fields */ }

Consumer preference backed by an infallible utility function.

Implementations

impl<F> Preference<F>

where F: Fn(&[f64]) -> f64,

pub fn new( utility_func: F, min_bounds: Vec<f64>, max_bounds: Vec<f64>, ) -> Result<Self, String>

Constructor - enforce the Axioms of Rationality upon creation on default config

pub fn with_validation( utility_func: F, min_bounds: Vec<f64>, max_bounds: Vec<f64>, validate: bool, ) -> Result<Self, String>

Constructor using the shared standard config with per-instance validation control.

pub fn with_config( utility_func: F, min_bounds: Vec<f64>, max_bounds: Vec<f64>, config: ValidationConfig, calc_config: CalcConfig, ) -> Result<Self, String>

Constructor - enforce or not enforce the Axioms of Rationality on customised config

pub fn get_utility(&self, bundle: &[f64]) -> f64

Getter for the utility of a specific consumption bundle

pub fn min_bounds(&self) -> &[f64]

pub fn max_bounds(&self) -> &[f64]

pub fn get_mu(&self, bundle: &[f64], good: usize) -> f64

Getter for marginal utility

This method allows user to access the marginal utility for a specified good, assuming consumption for all other goods in the bundle remains equal:

mu = (U(x + ep) - U(x - ep)) / 2

Arguments

• bundle - the bundle of goods in question
• good - index for the good to be evaluated

pub fn get_mrs( &self, bundle: &[f64], good_i: usize, good_j: usize, ) -> Result<f64, String>
