utils.Result
See theResult companion object
enum Result[+T, +E]

A type representing either a successful value or an error.

Result[T, E] is similar to Either[E, T] but with more intuitive naming where T represents the success type and E represents the error type. This is commonly used for error handling without exceptions.

Type parameters

E

the type of the error value

T

the type of the success value

Attributes

Example 
 val success: Result[Int, String] = Result.Success(42) val failure:
 Result[Int, String] = Result.Failure("Something went wrong")
val doubled = success.map(_ * 2) // Result.Success(84) val errorResult =
failure.map(_ * 2) // Result.Failure("Something went wrong")
