-### What it does
-Checks for the `as_bytes` method called on string literals
-that contain only ASCII characters.
-
-### Why is this bad?
-Byte string literals (e.g., `b"foo"`) can be used
-instead. They are shorter but less discoverable than `as_bytes()`.
-
-### Known problems
-`"str".as_bytes()` and the suggested replacement of `b"str"` are not
-equivalent because they have different types. The former is `&[u8]`
-while the latter is `&[u8; 3]`. That means in general they will have a
-different set of methods and different trait implementations.
-
-```
-fn f(v: Vec<u8>) {}
-
-f("...".as_bytes().to_owned()); // works
-f(b"...".to_owned()); // does not work, because arg is [u8; 3] not Vec<u8>
-
-fn g(r: impl std::io::Read) {}
-
-g("...".as_bytes()); // works
-g(b"..."); // does not work
-```
-
-The actual equivalent of `"str".as_bytes()` with the same type is not
-`b"str"` but `&b"str"[..]`, which is a great deal of punctuation and not
-more readable than a function call.
-
-### Example
-```
-let bstr = "a byte string".as_bytes();
-```
-
-Use instead:
-```
-let bstr = b"a byte string";
-```
