import { type ValitaResult } from "https://deno.land/x/valita@v0.3.8/mod.ts";
A validation/parsing success or failure.
Used by parsing-related methods where and both success and failure
cases are returned as values (instead of raising an exception on failure).
The most notable example is the Type.try(...) method.
The .ok property can to assert whether the value represents a success or
failure and access further information in a typesafe way.

Example 1
const t = v.string();
// Make parsing fail or succeed about equally.
const result = t.try(Math.random() < 0.5 ? "hello" : null);
if (result.ok) {
// TypeScript allows accessing .value within this code block.
console.log(`Success: ${result.value}`);
} else {
// TypeScript allows accessing .message within this code block.
console.log(`Failed: ${result.message}`);
