dspIncludes

function Dsp.includes(disposer: Dsp, value: (() => void) | Dsp): boolean;

O(n)

Example

import { Dsp } from "@monstermann/dsp";

const dsp = Dsp.create();
const cb = () => {};

Dsp.includes(dsp, cb); // false
const link = Dsp.add(dsp, cb);
Dsp.includes(dsp, cb); // true
Dsp.unlink(dsp, link);
Dsp.includes(dsp, cb); // false
