monad-validate v1.2.0.0 Release Notes

Release Date: 2019-08-10 // about 5 years ago
    • ➕ Added the exceptToValidate, exceptToValidateWith, validateToError, and validateToErrorWith functions for converting between different error-raising monads.
    • ✂ Removed the DefaultSignatures-based default methods for MonadValidate in favor of a WrappedMonadTrans newtype available from Control.Monad.Validate.Class that can be used to derive instances using DerivingVia.
    • ➕ Added a default implementation of dispute in terms of refute and tolerate and added their equivalence as a law for MonadValidate.

Previous changes from v1.1.0.0

    • ➕ Added the tolerate method to MonadValidate, which allows relaxing validation errors from fatal to nonfatal.
    • ➕ Added the embedValidateT and mapErrors functions, which can be used together to locally alter the type of validation errors in ValidateT computations.
    • ✂ Removed the MonadValidate instance for ContT, which is no longer possible to implement due to the addition of tolerate.
