   = note: the literal `0xFEDCBA98` (decimal `4275878552`) does not fit into the type `i32` and will become `-19088744i32`
   = help: consider using the type `u32` instead
   = note: `#[deny(overflowing_literals)]` on by default
   help: to use as a negative number (decimal `-19088744`), consider using the type `u32` for the literal and cast it to `i32`
