When to panic in Go versus Rust
WHAT IT TESTS: error philosophy and panic boundaries. OUTLINE: both reserve panic for unrecoverable bugs and use values, Result or error, for expected failures; Rust's type system pushes more cases to Result.
WHAT IT TESTS: whether you grasp that panic signals programmer error, not expected failure, in both languages. ANSWER OUTLINE: both reserve panic for unrecoverable states like invariant violations and use ordinary values for expected errors, Go's error return and Rust's Result. Rust's type system nudges fallible operations into Result and Option so fewer things panic, though unwrap and indexing can; Go uses panic mainly for bugs and recovers at boundaries.
