Result
The result of a promise.
enum ResultThe result of a promise.
enum Resultimport JavaScriptKitfinal class JSPromiseA wrapper around the JavaScript Promise class
case success(JSValue)The promise resolved with a value.
case failure(JSValue)The promise rejected with a value.
convenience init?(_ jsObject: JSObject) Creates a new JSPromise instance from a given JavaScript Promise object. If jsObject is not an instance of JavaScript Promise, this initializer will return nil.
convenience init(resolver: @escaping (@escaping (Result) -> Void) -> Void) Creates a new JSPromise instance from a given resolver closure. The closure is passed a completion handler. Passing a successful Result to the completion handler will cause the promise to resolve with the corresponding value; passing a failure Result will cause the promise to reject with the corresponding value. Calling the completion handler more than once will have no effect (per the JavaScript specification).
init(unsafelyWrapping object: JSObject) This private initializer assumes that the passed object is a JavaScript Promise
static var constructor: JSFunction? { get }static func construct(from value: JSValue) -> Self? Creates a new JSPromise instance from a given JavaScript Promise object. If value is not an object and is not an instance of JavaScript Promise, this function will return nil.
static func reject(_ reason: ConvertibleToJSValue) -> JSPromise static func resolve(_ value: ConvertibleToJSValue) -> JSPromise let jsObject: JSObjectThe underlying JavaScript Promise object.
@discardableResult func `catch`(failure: sending @escaping (sending JSValue) async throws -> ConvertibleToJSValue) -> JSPromise Schedules the failure closure to be invoked on rejected completion of self.
@discardableResult func `catch`(failure: @escaping (sending JSValue) -> ConvertibleToJSValue) -> JSPromise Schedules the failure closure to be invoked on rejected completion of self.
@discardableResult func finally(successOrFailure: @escaping () -> Void) -> JSPromise Schedules the failure closure to be invoked on either successful or rejected completion of self.
func jsValue() -> JSValue The underlying JavaScript Promise object wrapped as JSValue.
@discardableResult func then(success: @escaping (JSValue) -> ConvertibleToJSValue) -> JSPromise Schedules the success closure to be invoked on successful completion of self.
@discardableResult func then(success: sending @escaping (sending JSValue) async throws -> ConvertibleToJSValue) -> JSPromise Schedules the success closure to be invoked on successful completion of self.
@discardableResult func then(success: sending @escaping (sending JSValue) async throws -> ConvertibleToJSValue, failure: sending @escaping (sending JSValue) async throws -> ConvertibleToJSValue) -> JSPromise Schedules the success closure to be invoked on successful completion of self.
@discardableResult func then(success: @escaping (sending JSValue) -> ConvertibleToJSValue, failure: @escaping (sending JSValue) -> ConvertibleToJSValue) -> JSPromise Schedules the success closure to be invoked on successful completion of self.
protocol EquatableA type that can be compared for value equality.
static func != (lhs: Self, rhs: Self) -> Bool Returns a Boolean value indicating whether two values are not equal.
