left

import { left } from "https://github.gh-proxy.cn/raw.githubusercontent.com/baetheus/fun/main/async_either.ts";

Constructs a AsyncEither from a value and wraps it in an inner Left traditionally signaling a failure.

@example

import * as AE from "./async_either.ts";

const left = AE.left(1);

const result = await left(); // Left(1);

function left<B, A = never>(left: B): AsyncEither<B, A>;

left<B, A = never>(left: B): AsyncEither<B, A>

A = never

left: B
