AnyErrorConvertible

Help convert Error to any type.

Usage

This framework has AnyErrorConvertible protocol and AnyErrorTranslator struct.

You can implement your own error conversion logic.

Core Usecase

For example, the following code.

import AnyErrorConvertible

enum ConnectionError: AnyErrorConvertible {
    case notFound
    case internal
    case unknown

    static func make(_ error: Error) -> Self {
        // Please your logic.
    }
}

let error = ... // This error is `Swift.Error` type which is from URLSession, CoreData and so on.
let connectionError = AnyErrorTranslator<ConnectionError>.translate(error)
switch connectionError {
case .notFound:
    print("Connection not found.")
case .internal:
    print("Occurred internal error")
case .unknown:
    print("Unknown error")
}

RxSwiftCommunity/Action Usecase

import Action
import AnyErrorConvertible
#if SWIFT_PACKAGE
import AnyErrorConvertibleAction
#endif
import RxSwift

let action: Action<Void, Void> = .init { /* Any observable */ }
_ = action.anyErrorTranslate<ConnectionError.self>
    .subscribe(onNext: { connectionError in
        switch connectionError {
        case .notFound:
            print("Connection not found.")
        case .internal:
            print("Occurred internal error")
        case .unknown:
            print("Unknown error")
        }
    })
action.execute()
