Struct good_lp::variable::VariableDefinition

pub struct VariableDefinition { /* fields omitted */ }

Defines the properties of a variable, such as its lower and upper bounds.

Implementations

impl VariableDefinition

pub fn new() -> Self

Creates an unbounded continuous linear variable

pub fn bounds<N: Into<f64> + Copy, B: RangeBounds<N>>(self, bounds: B) -> Self

Set the lower and/or higher bounds of the variable

Examples

assert_eq!(
    variable().bounds(1..2),
    variable().min(1).max(2)
);

assert_eq!(
    variable().bounds(1..),
    variable().min(1)
);

assert_eq!(
    variable().bounds(..=2),
    variable().max(2)
);

pub fn min<N: Into<f64>>(self, min: N) -> Self

Set the lower bound of the variable

pub fn max<N: Into<f64>>(self, max: N) -> Self

Set the higher bound of the variable

pub fn clamp<N1: Into<f64>, N2: Into<f64>>(self, min: N1, max: N2) -> Self

Set both the lower and higher bounds of the variable

Trait Implementations

impl PartialEq<VariableDefinition> for VariableDefinition

fn eq(&self, other: &VariableDefinition) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &VariableDefinition) -> bool

This method tests for !=.
