Struct limn_core::prelude::Constraint
[−]
pub struct Constraint(_);
A constraint, consisting of an equation governed by an expression and a relational operator, and an associated strength.
Methods
impl Constraint
pub fn new(e: Expression, op: RelationalOperator, strength: f64) -> Constraint
Construct a new constraint from an expression, a relational operator and a strength.
This corresponds to the equation e op 0.0
, e.g. x + y >= 0.0
. For equations with a non-zero
right hand side, subtract it from the equation to give a zero right hand side.
pub fn expr(&self) -> &Expression
The expression of the left hand side of the constraint equation.
pub fn op(&self) -> RelationalOperator
The relational operator governing the constraint.
pub fn strength(&self) -> f64
The strength of the constraint that the solver will use.
