Pudu Validator

pudu-lang-validator is a typed validation package for Pudu, written in Pudu. You describe rules for a record with ordinary Pudu functions, run them against a value, and get back an ordered list of failures. Each failure carries a property path, a message, a code, a severity, and application state.

This wiki documents the 0.1.1 API. Every program in it was checked with pudu check and run with pudu run against @chrismichaelps/pudu-lang-validator@0.1.1. The versioned design notes live in the repository wiki/ directory.
