/// ### Example
/// ```rust
/// let string = String::with_capacity(1);
/// let ptr = string.as_ptr() as *mut u8;
/// let mut vec = Vec::<u8>::with_capacity(1);
/// let ptr = vec.as_ptr() as *mut u8;
/// unsafe { ptr.write(4) }; // UNDEFINED BEHAVIOUR
/// ```
/// Use instead:
/// ```rust
/// let mut string = String::with_capacity(1);
/// let ptr = string.as_mut_ptr();
/// let mut vec = Vec::<u8>::with_capacity(1);
/// let ptr = vec.as_mut_ptr();
/// unsafe { ptr.write(4) };
/// ```
