ResultK

ResultK provides Result suitable to Swift’s untyped throws. ResultK‘s Result type does not have the second type parameter to specify the error type unlike antitypical/Result.

let a: Result<Int> = Result { try primeOrThrow(2) }
switch a {
case let .success(value):
    print(value)
case let .failure(error):
    print(error)
}

Result is a monad. map and flatMap are available for Result.

let b: Result<Int> = Result(3)
let sum: Result<Int> = a.flatMap { a in b.map { b in a + b } } // Result(5)
