Struct LinearIntegerExpr 

pub struct LinearIntegerExpr<T: Display + Debug + Clone> {
    pairs: Vec<AtomFactorPair<T>>,
}

Type to represent a linear arithmetic expression

Fields

pairs: Vec<AtomFactorPair<T>>

Pairs part of a sum

Implementations

impl<T: Display + Debug + Clone> LinearIntegerExpr<T>

pub fn get_const_factor(&self) -> Fraction

Get the constant factor of the expression

For an expression of the form a * x + b * y + p * z + c, where a, b and p are coefficients and x,y,z are parameters and c a constant, this function returns c.

pub fn get_atom_factor_pairs(&self) -> impl Iterator<Item = (&T, &Fraction)>

Get all atom factor pairs of the expression

For an expression of the form a * x + b * y + p * z + c, where x and y are atoms, a and b are their coefficients, p is a parameter, and z is its coefficient, this function returns the pairs (x, a), (y, b).

pub fn get_param_factor_pairs( &self, ) -> impl Iterator<Item = (&Parameter, &Fraction)>

Get all parameter factor pairs of the expression

For an expression of the form a * x + b * y + p * z + c, where x, y, z are parameters and a, b, p are their coefficients, this function returns the pairs (p, z), where p is the parameter and z is its coefficient.

Trait Implementations

impl<T: Clone + Display + Debug + Clone> Clone for LinearIntegerExpr<T>

fn clone(&self) -> LinearIntegerExpr<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Display + Debug + Clone> Debug for LinearIntegerExpr<T>

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

Formats the value using the given formatter.

impl<T: Display + Debug + Clone> Display for LinearIntegerExpr<T>

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

Formats the value using the given formatter.

impl<T: PartialEq + Display + Debug + Clone> PartialEq for LinearIntegerExpr<T>

fn eq(&self, other: &LinearIntegerExpr<T>) -> 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.

impl<T: Atomic> TryFrom<NoDivIntegerExpr<T>> for LinearIntegerExpr<T>

type Error = ConstraintRewriteError

The type returned in the event of a conversion error.

fn try_from(value: NoDivIntegerExpr<T>) -> Result<Self, Self::Error>

Performs the conversion.
