dry-schema provides a DSL for defining schemas with keys and rules that should be applied to values. It supports coercion, input sanitization, custom types and localized error messages (with or without I18n gem). It's also used as the schema engine in dry-validation.

Inspired by dry-initializer and virtus, portrayal is a minimalist gem that takes a somewhat different approach to building struct-like classes. It steps away from types, coersion, and writer methods in favor of encouraging well-designed constructors. Read more in the Philosophy section of the README.
