Creates a set from an async iterable.

import { toSet } from "./collections.ts";

async function* gen() { yield "foo"; yield "bar"; yield "baz"; }
const set = await toSet(gen());

The set variable will be a set like new Set(["foo", "bar", "baz"]).

Duplicate elements are removed except for the first occurrence of each element. E.g.:

import { toSet } from "./collections.ts";

async function* gen() { yield "foo"; yield "bar"; yield "foo"; }
const set = await toSet(gen());

The set variable will be a set like new Set(["foo", "bar"]).

Note that the iterable source is assumed to be finite; otherwise, it will never return. The following example will never return:

import { toSet } from "./collections.ts";
import { count } from "./infinite.ts";

await toSet(count(0));
