/// First, all of `src`'s `PtrInner` invariants are upheld. `src`'s address and

/// - If its referent is not zero sized, then it still has valid provenance for
/// its referent, which is still entirely contained in some Rust allocation,

/// - If its referent is not zero sized, then it addresses a byte range entirely

/// - The length of its referent fits in an `isize`
/// - Its referent does not wrap around the address space

/// `'a`
