Struct Expression 

pub struct Expression {
    pub terms: Vec<Term>,
    pub constant: f64,
}

A linear expression: Σ coefficient·variable + constant.

Fields

terms: Vec<Term>

Weighted variable terms.

constant: f64

Constant offset.

Implementations

impl Expression

pub fn new(terms: Vec<Term>, constant: f64) -> Self

Construct from an explicit list of terms and a constant.

pub fn from_constant(c: f64) -> Self

A constant expression with no variables.

pub fn from_variable(v: Variable) -> Self

An expression representing a single variable with coefficient 1.0.

Trait Implementations
