The whole point is to gracefully handle errors and not let panics make it to production code. But <code>unwrap()</code> assumes there's a value to extract without safeguards.</p><p>I use <code>.unwrap()</code> sometimes! Usually when there's a logical guarantee that the result can never be an error.

Open post jerome @jerome@strings.io · 9mo ago Replying to @tojiro@mastodon.social A year ago I installed solar panels+batteries, and now have a year of electric bills to compare. 2024: $4,133.13 2025: $655.62! The entire year was less than the previous year's July bill. Also got an EV last year so that amount ALSO includes my "gas" costs from charging at home. (~$1500/year with my prev gas car.) Hard to think of a pair of purchases I've been happier with! @tojiro what equipment did you get? Sounds interesting!
