Unwrap

Definitions

1. An operation that extracts the inner value from a wrapper type such as Option or Result, panicking or throwing if the wrapper contains no value (None) or an error. Common in Rust, Swift, and other languages with algebraic types.

   In plain English: Opening a container that either holds a value or an error — if it's an error and you unwrap it, the program crashes immediately.

   Example: "We unwrap the config file path because if it's missing, there's nothing sensible the program can do anyway."
