A Swift microframework providing a Result<Value, Error> type that models operations as either success or failure, similar to Optional but with an associated error. It offers composable map/flatMap operations as an alternative to Swift's throw-based error handling.

Use cases

• model success/failure of operations in Swift
• return errors as values instead of throwing
• compose fallible operations with map and flatMap
• pattern match on operation outcomes with switch
• share a common Result type across Swift frameworks

When to choose

• you're on an older Swift codebase (pre-5.0) without a native Result type
• you want composable, value-based error handling with map/flatMap
• you need interoperability with other frameworks using this Result type

When to avoid

• you're on Swift 5+ where Result is in the standard library
• you prefer Swift's native throw/catch error handling
• starting a new project with no legacy dependencies on this library
