Merge #498: Fix a load of non-controversial clippy warnings
6b6f808 Use any combinator (Tobin C. Harding) 6088c25 Use {} instead of explicit return (Tobin C. Harding) 06c9617 Remove unnecessary cast (Tobin C. Harding) eb38507 Do not use bool in assert_eq macro (Tobin C. Harding) 3c46e4c Use expect_err (Tobin C. Harding) 9c377b2 Remove useless use of format (Tobin C. Harding) bf44938 Remove unneeded calls to clone (Tobin C. Harding) 227a3a9 Remove identical if blocks (Tobin C. Harding) 45091a8 Remove unneeded explicit lifetimes (Tobin C. Harding) 2e70cd0 Do not manually convert bool to integer (Tobin C. Harding) c4ab53e Use &str not &String (Tobin C. Harding) b81f08c Return result of function call (Tobin C. Harding) fc37f41 Use unwrap_or_default (Tobin C. Harding) f0820ce Remove redundant explicit references (Tobin C. Harding) 64c6e51 Fix pattern matching ref/deref (Tobin C. Harding) a923855 Do not use redundant closures (Tobin C. Harding) 4ab7e7a Use terse struct construction form (Tobin C. Harding) 9d1a984 Remove 'static from &str (Tobin C. Harding) b9df24c Clear block can be collapsed warnings (Tobin C. Harding) Pull request description: I've attempted to only do the easy, and non-controversial ones in this PR. Each warning is a separate patch (except `clone` warnings). `rustfmt` run on each patch.
