Result initialized with an async operation

Result+Task.swift

extension Result where Failure == Error {
  init(_ task: @escaping () async throws -> Success) async {
    self = await withCheckedContinuation { [task] continuation in
      Task {
        do {
          continuation.resume(returning: .success(try await task()))
        } catch {
          continuation.resume(returning: .failure(error))
        }
      }
    }
  }
}

Or if you need a throwing variant:

extension Result {
  init(_ task: @escaping () async throws -> Success) async throws {
    self = try await withCheckedThrowingContinuation { [task] continuation in
      Task {
        do {
          continuation.resume(returning: .success(try await task()))
        } catch let error as Failure {
          continuation.resume(returning: .failure(error))
        } catch {
          continuation.resume(throwing: error)
        }
      }
    }
  }
}

I am trying to wrap my head around this, is it possible to show an example on how it can be used at the call site?

You get a result out of a throwing async task, like so:

let webResponse = await Result { try await URLSession.shared.data(from: url) }
