/*
In Rust, the largest primitive integer type is u64 (unsigned 64‑bit).
Its maximum value is about 1.84 × 10^19.
A petabyte fits comfortably:
1 PiB = 2^50 = 1,125,899,906,842,624 bytes
1 PB = 10^15 = 1,000,000,000,000,000 bytes
Rust allows:
- bit shifting on integer literals
- readable numeric literals with underscores
- compile‑time constant evaluation
