 Did you know that the standard library is full of useful checks that users never get to see?

-There are plenty of debug assertions in the standard library that will do things like check that `char::from_u32_unchecked` is called on a valid `char`, that `CStr::from_bytes_with_nul_unchecked` does not have internal nul bytes, or that pointer functions such as `read`, `copy`, or `copy_nonoverlapping` are called on suitably aligned non-null (and non-overlapping) pointers.

 However, the regular standard library that is distributed by rustup is compiled without debug assertions, so there is no easy way for users to benefit from all this extra checking.
