kotlin coroutine context
It is an indexed set of Element instances where every element in this set has a unique Key. EmptyCoroutineContext - Does not change coroutine behavior at all. Like an empty map. CoroutineName - Sets a name of a coroutine for debugging purposes. Job - Lifecycle of a coroutine. Can be used to cancel coroutine. A coroutine is responsible for all children with the same Job. It waits for them and cancels all of them if any had an error (To make children independent use SupervisorJob). CoroutineExceptionHandler - Used to set exception handling for uncaught exceptions. ContinuationInterceptor - Intercepts continuation. Mainly used by dispatchers.
