OpenAPI 3.1 OpenAPI 3.1 uses the latest JSON Schema, and the recommended way to annotate individual enum values in JSON Schema is to use oneOf+const instead of enum. This way you can specify both custom names (title) and descriptions for enum values. Severity: type: integer oneOf: – title: HIGH const: 2 description: An urgent problem … Read more
I also had this problem. Easy way to get around it: add a + sign before your variable in the switch, i.e. switch (+editMode) { case EditMode.Delete: … break; case EditMode.Edit: … break; default: … break; }
Assuming your native code is enum shape_type_e { stUNHANDLED = 0, //!< Unhandled shape data. stPOINT = 1 //!< Point data. … }; and your managed code is public enum class ShapeType { Unhandled = 0, Point = 1, … }; You can cast from the native to the managed using shape_type_e nativeST = stPOINT; … Read more
First, you need to update your DropdownButton type argument to ClassType and not String. In Dart, an enum declaration creates a new type, not Strings. DropdownButton(…); Next, you need to change the enum names. An enum has to be a valid dart identifier, meaning it can’t contain the symbol -. enum ClassType {A, B, C, … Read more
Create an enum from a raw using the failable initializer with rawValue and get the raw value using the attribute rawValue. if let a = TestEnum(rawValue: “a”) { println(a.rawValue) } Read the changelog for more information.
Enum variants have three possible syntaxes: unit enum A { One } tuple enum B { Two(u8, bool) } struct enum C { Three { a: f64, b: String } } You have to use the same syntax when pattern matching as the syntax the variant was defined as: unit match something { A::One => … Read more
Can traits be used on enum types? Yes. In fact, you already have multiple traits defined for your enum; the traits Debug, Copy and Clone: #[derive(Debug, Copy, Clone)] pub enum SceneType The problem is that you aren’t attempting to implement Playable for your enum, you are trying to implement it for one of the enum’s … Read more
As stated in other answers, you can reference any value of the enum that exists by name, but not construct a new one. That does not prevent you from doing something similar to what you were trying… // wrong, it is a sealed hierarchy, you cannot create random instances val bitCount : BitCount = BitCount(32) … Read more
An enum can’t be directly extended, but you use the same composition trick one would use with structs (that is, with a struct, one would have a field storing an instance of the ‘parent’). enum Base { Alpha, Beta(usize), } enum Extended { Base(Base), Gamma } If you wish to handle each case individually, this … Read more
You can build a struct that conforms to the RawOptionSet protocol, and you’ll be able to use it like the built-in enum type but with bitmask functionality as well. The answer here shows how: Swift NS_OPTIONS-style bitmask enumerations.
