Struct Constraint

pub struct Constraint(/* private fields */);

Constraint.

Implementations

impl Constraint

pub fn kind(&self) -> &ConstraintKind

Gets constraint kind.

pub fn label(&self) -> &str

Gets constraint label.

pub fn lhs(&self) -> &Node

Gets constraint left-hand-side.

pub fn new( lhs: Node, kind: ConstraintKind, rhs: Node, label: &str, ) -> Constraint

Creates new constraint.

pub fn rhs(&self) -> &Node

Gets constraint right-hand-side.

pub fn violation(&self, var_values: &HashMap<&Node, f64>) -> f64

Computes constraint violation given variable values.

Trait Implementations

impl Clone for Constraint

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConstraintStd for Constraint

fn std_components( &self, arow: &mut usize, jrow: &mut usize, ) -> ConstraintStdComp

Gets standard components of constraint.

impl Debug for Constraint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Display for Constraint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Constraint

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Constraint

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
