fromPromise<T>(promise: T | Promise<T> | PromiseLike<T>): Source<T>
Convert a Promise to an event source
Each time the resulting source is subscribed to, it will emit an event for
the result of the promise, then close the connection. (Unless the promise is
rejected, in which case the connection throws and closes each time the source
is subscribed.) Non-native promises and non-promise values are converted
using Promise.resolve().
