init(continuation:function:)
Creates a checked continuation from an unsafe continuation.
Declaration
init(continuation: UnsafeContinuation<T, E>, function: String = #function)Parameters
- continuation:
An instance of
UnsafeContinuationthat hasn’t yet been resumed. After passing the unsafe continuation to this initializer, don’t use it outside of this object. - function:
A string identifying the declaration that is the notional source for the continuation, used to identify the continuation in runtime diagnostics related to misuse of this continuation.
Discussion
Instead of calling this initializer, most code calls the withCheckedContinuation(function:_:) or withCheckedThrowingContinuation(function:_:) function instead. You only need to initialize your own CheckedContinuation<T, E> if you already have an UnsafeContinuation you want to impose checking on.
