panic!
Rust's immediate-stop tool for unrecoverable states
Core Idea
[[panic|panic!]] is the Rust macro used when execution cannot safely continue. It is less about modeling recoverable failure and more about surfacing a broken assumption or impossible state immediately.
Why It Matters Here
Mathbong uses panic when discussing unwrap, expect, test failures, and debugging guardrails. The real lesson is learning which failures should be returned as [[result|Result]] values and which ones truly deserve an immediate stop.
