Result and Option Types

← Back to Modern and Functional Patterns

Error handling without exceptions. Explicit types that represent either success/failure (Result) or presence/absence (Option/Maybe). Force callers to handle error cases at compile time, making error handling explicit and exhaustive. Common in Rust, Haskell, and modern TypeScript.

Key Properties

• Explicit Error Handling
• Pattern Matching
• Railway Oriented Programming
