Features

Codable

There are several extensions on KeyedDecodingContainer. Most of which are heavily inspired by Unbox.

THE PLANET

Throughout the Codable examples, the following struct is used:

import CELLULAR

public struct Planet: Codable {

    public var discoverer: String

    public var hasRingSystem: Bool

    public var numberOfMoons: Int

    public var distanceFromSun: Float // 10^6 km

    public var surfacePressure: Double? // bars

    public var atmosphericComposition: [String]

1. Allows Foundation types to be inferred on value assignment

    public init(from decoder: Decoder) throws {
	let container = try decoder.container(keyedBy: CodingKeys.self)

	discoverer = try container.decode(forKey: .discoverer) // String
	hasRingSystem = try container.decode(forKey: .hasRingSystem) // Bool
	numberOfMoons = try container.decode(forKey: .numberOfMoons) // Int
	distanceFromSun = try container.decode(forKey: .distanceFromSun) // Float

2. Even Optional holding these types may be inferred

	surfacePressure = try container.decode(forKey: .surfacePressure) // Double?

3. Allows instances in collections to fail decoding

	atmosphericComposition = try container.decode(forKey: .atmosphericComposition, allowInvalidElements: true) ?? []
    }
}

Locking

TODO

Result

A type that represents either a success value or failure value, both of which may be of different types. This is similar to Swift’s native Optional type, yet, instead of nil as error indicating, it allows none-nil failure returns with additional information.

import CELLULAR

public enum Result<Success, Failure> {
    case success(Success)
    case failure(Failure)
}
