monad-validate: A monad transformer for data validation.

[ control, library ] [ Propose Tags ] [ Report a vulnerability ]

Provides the ValidateT monad transformer, designed for writing data validations that provide high-quality error reporting without much effort. ValidateT automatically exploits the data dependencies of your program—as encoded implicitly in uses of fmap, <*>, and >>=—to report as many errors as possible upon failure instead of completely aborting at the first one. See Control.Monad.Validate for more information.
