pub struct LinExpr { /* fields omitted */ }
Expand description
Linear expression of variables
Represents an affine expression of variables: a constant term plus variables multiplied by coefficients.
A LinExpr object is typically created using Expr::into_linexpr. Most Model methods take
Expr as arguments instead of LinExpr, so converting to LinExpr is rarely needed.
Create new an empty linear expression.
Does this expression evaluate (close to) 0.0f64?
assert!(grb::expr::LinExpr::new().is_empty());
Add a linear term into the expression.
Add a constant into the expression.
Set the constant offset, returning the old one
Get actual value of the expression.
Decompose into variables, their coefficients and the offset, respectively.
number of linear terms in the expression (excluding the constant)
Returns an iterator over the terms excluding the offset (item type is (&Var, &f64))
Multiply expression by a scalar
Remove variable terms whose coefficients are less than or equal to f64::EPSILON.
