Struct Problem

Source

pub struct Problem<Var, Value> {
    pub constraints: Vec<Box<dyn Constraint<Var, Value>>>,
    pub range: HashSet<Var, BuildHasherDefault<FxHasher>>,
}

Expand description

A constraint satisfaction problem consisting of constraints and a range of variables to solve for. The problem is considered solved when all variables in the range are assigned.

Fields§

§constraints: Vec<Box<dyn Constraint<Var, Value>>>

The list of constraints that must be satisfied

§range: HashSet<Var, BuildHasherDefault<FxHasher>>

The set of variables that must be assigned a value for the problem to be considered solved
