TypedCache is a Ruby caching library designed to eliminate common caching pitfalls by providing a monadic, type-safe API that makes cache operations explicit and predictable. Cache interactions are first-class operations with comprehensive error handling and transparent state management. The library supports wrapping other caching libraries via custom backends and ActiveSupport::Cache is supported out of the box.
