Internal implementation detail, do not use directly. Will be made internal in v8.
If you have implemented an operator using lift, it is recommended that you create an
operator by simply returning new Observable() directly. See "Creating new operators from
scratch" section here: https://rxjs.dev/guide/operators
import { Observable } from "https://deno.land/x/rxjs@v1.0.2/mod.ts";
Creates a new Observable, with this Observable instance as the source, and the passed operator defined as the new observable's operator.
