Enumerated Types (Enums): Definition, Usage, and Underlying Implementations of Structured Data in 22

Have you ever wondered how enumerated types are truly defined, implemented, and optimized across languages as different as Rust, Haskell, MATLAB, and C++?

Enumerated Types (Enums): Definition, Usage, and Underlying Implementations of Structured Data in 22 Languages is a comprehensive, technical-informal guide that explores how enums evolve from simple constants to powerful, structured data tools. Covering languages across paradigms-imperative, functional, declarative, and scientific-it bridges foundational syntax, flag manipulation, type safety, control flow integration, and internal compiler representation.

Through 6 well-structured parts and 24 concise modules, this book balances explanation and practicality. It compares simple and typed enums, string-based and flag enums, scoped variants, and their performance trade-offs-all while offering syntax comparisons, best practices, and warnings on misuse. Whether you're coding in Ada, Python, Swift, or XSLT, you'll gain real insights into making enums readable, safe, and scalable.

If you're a cross-language developer, technical writer, educator, or systems architect, this book will transform how you think about and use enums. Let's enumerate excellence-across 22 languages.
