Enum SoftKey 

pub enum SoftKey {
    Var(VarId),
    Array(ArrayId),
    ArraySize(ArrayId),
}

A random variable a disable soft can name, or a soft constraint can directly mention (18.5.13.2: “including array.size”).

Variants

Var(VarId)

A scalar random variable (or one element of a fixed array).

Array(ArrayId)

Some element of a dynamic array or queue, or the array as a whole when it is a disable soft target.

ArraySize(ArrayId)

The size of a dynamic array or queue.

Implementations

impl SoftKey

pub fn disables(self, mention: SoftKey) -> bool

Whether a disable soft on self reaches a soft constraint that mentions mention (18.5.13.2: only where the variable directly appears). Naming a whole array reaches its elements and its size; naming A.size only the size.
