Overview

Primer::FetchOrFallbackHelper A little helper to enable graceful fallbacks

Use this helper to quietly ensure a value is one that you expect:

allowed_values - allowed options for value given_value - input being coerced fallback - returned if given_value is not included in allowed_values deprecated_values - deprecated options for value. Will warn of deprecation if not in production

fetch_or_fallback(, 5, 2) => 2 fetch_or_fallback(, 1, 2) => 1 fetch_or_fallback(, nil, 2) => 2

With deprecations: fetch_or_fallback(, 3, 2, deprecated_values: [3]) => 3 fetch_or_fallback(, nil, 2, deprecated_values: [3]) => 2
