Function safelyTry

Given a function which takes no arguments and returns a Promise, return a Task<T, unknown> for the result of invoking that function. This safely handles functions which fail synchronously or asynchronously, so unlike Task.try is safe to use with values which may throw errors before producing a Promise.

Examples

import { safelyTry } from 'true-myth/task';

function throws(): Promise<T> {
  throw new Error("Uh oh!");
}

// Note: passing the function by name, *not* calling it.
let theTask = safelyTry(throws);
let theResult = await theTask;
console.log(theResult.toString()); // Err(Error: Uh oh!)
