Defines a constraint.

Interfaces

ConstraintInterface
DO NOT IMPLEMENT this interface. It is only meant for usage as a type hint in libraries relying on composer/semver but creating your own constraint class that implements this interface is not a supported use case and will cause the composer/semver components to return unexpected results.
