-### What it does
-Checks for usage of `libc::strlen` on a `CString` or `CStr` value,
-and suggest calling `as_bytes().len()` or `to_bytes().len()` respectively instead.
-
-### Why is this bad?
-This avoids calling an unsafe `libc` function.
-Currently, it also avoids calculating the length.
-
-### Example
-```
-use std::ffi::CString;
-let cstring = CString::new("foo").expect("CString::new failed");
-let len = unsafe { libc::strlen(cstring.as_ptr()) };
-```
-Use instead:
-```
-use std::ffi::CString;
-let cstring = CString::new("foo").expect("CString::new failed");
-let len = cstring.as_bytes().len();
-```
