Minimizes two constraints.

Compares two constraints and determines if one is a subset of the other. If this is the case, the constraint that is a subset is returned. For example, if called with '^6.2' and '^6.3' the function will return '^6.3'. If neither constraint is a subset then the constraints are compacted and the intersection is returned. For example, if called with ">=10.3" and "^10.4 || ^11" the function will return ">=10.4.0.0-dev, <12.0.0.0-dev".

Parameters

\Composer\Semver\VersionParser $version_parser: A version parser.

string $constraint_a: A constraint to compact.

string $constraint_b: A constraint to compact.

Return value

string The compacted constraint.

Throws

\LogicException Thrown when the provided constraints have no intersection.
