Question
You ask an AI to explain this Rust config loader before wiring it into a long-running server. The agent says: "It gracefully loads config and returns a Result, so any parse error or missing file propagates to the caller for handling — no way it can crash the process." Is that explanation accurate, and how do you verify the no-crash claim before depending on it in a service that must stay up?
fn load_config(path: &str) -> Result<Config, ConfigError> { let text = std::fs::read_to_string(path).unwrap(); let cfg: Config = serde_json::from_str(&text).expect("valid config"); Ok(cfg)}Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
