//!     overflow the pointer type of the process it describes a range in.
//!
//! This class checks bases of type `ValueType` and sizes of type `SizeType`
//! against a process whose pointer type is either 32 or 64 bits wide.
//!
//! Aside from varying the overall range on the basis of a process’ pointer type
//! width, this class functions very similarly to CheckedRange.
