import { R } from "https://deno.land/x/ahh@v0.10.0/src/result/mod.ts";
Returns whether res strictly equals value, or
false if it is an Ok.
This only checks whether res and value have the
same name and message.
Examples
import { R } from "./mod.ts";
console.log(R.containsErr(1, Error())); // false
console.log(R.containsErr(Error(), Error())); // true
console.log(R.containsErr(Error(), Error("nope"))); // false
