bors 74285eb3a8 Auto merge of #78088 - fusion-engineering-forks:panic-fmt-lint, r=estebank ... Add lint for panic!("{}") This adds a lint that warns about `panic!("{}")`. `panic!(msg)` invocations with a single argument use their argument as panic payload literally, without using it as a format string. The same holds for `assert!(expr, msg)`. This lints checks if `msg` is a string literal (after expansion), and warns in case it contained braces. It suggests to insert `"{}", ` to use the message literally, or to add arguments to use it as a format string.  This lint is also a good starting point for adding warnings about `panic!(not_a_string)` later, once [`panic_any()`](https://github.com/rust-lang/rust/pull/74622) becomes a stable alternative.		2020-11-20 03:40:20 +00:00
