This library provides features to validate the values that have been assigned to Ballerina types.

The Ballerina constraint library facilitates APIs to do validations on the Ballerina types further with the use of annotations.

Issues and Projects tabs are disabled for this repository as this is part of the Ballerina Standard Library. To report bugs, request new features, start new discussions, view project boards, etc., go to the Ballerina Standard Library parent repository.
