Access environment variables. Also includes presence validation, type coercion and default values.

A small collection of extensions useful for data coercion and validation

Provides coercions for ActiveModel objects

Type system for Ruby supporting coercions, constraints and complex types like structs, value objects, enums etc

Easily filters type coercion in jsonapi-resources.

Clock interface with support for UTC and local timezones, timezone coercion, and dependency substitution

Rack parameter validation and type coercion.

Type Coercion & Type Enhancement

Generates modules that provide conventional value semantics for a given set of attributes. The behaviour is similar to an immutable `Struct` class, plus extensible, lightweight validation and coercion.

Emu acts as a replacement for ad-hoc type coercions and strong_parameters.

Simple and composable validation and coercion of data structures inspired by clojure specs

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.

A type coercion lib works with Sorbet's static type checker and type definitions; raises an error if the coercion fails.

Safe type coercion for the Jet Toolkit.

Contracts for string coercion
