#[non_exhaustive]pub enum ConstraintStrength {
Required,
Strong,
Medium,
Weak,
}
Expand description
The strength of a constraint, expressed as a symbolic constant.
The strength of a Constraint
can be expressed with any positive
integer; the values of this enumeration can be used for readability.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Required
The constraint is required towards solving the layout
Strong
A strong constraint
Medium
A medium constraint
Weak
A weak constraint
