Struct LinExpr 

pub struct LinExpr {
    pub coeffs: BTreeMap<String, i64>,
    pub constant: i64,
}

A linear expression Σ cⱼ·xⱼ + constant over the integers (zero coefficients pruned, so equality is canonical).

Fields

coeffs: BTreeMap<String, i64>

constant: i64

Implementations

impl LinExpr

pub fn sub(&self, o: &Self) -> Self

pub fn is_const(&self) -> bool

True when this is a bare integer constant (no variables remain).

Trait Implementations

impl Clone for LinExpr

fn clone(&self) -> LinExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinExpr

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

Formats the value using the given formatter.

impl PartialEq for LinExpr

fn eq(&self, other: &LinExpr) -> 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.
