Environment Details

The exact output of compiled binaries will vary slightly depending on your compiler version, target architecture, and operating system. To make results reproducible, here are the specifics of the environment I’ll be using throughout this book:

rustc --version --verbose
rustc 1.88.0 (6b00bc388 2025-06-23)

The host field (x86_64-pc-windows-msvc) indicates the target platform: 64-bit Intel/AMD (x86_64), Windows OS (windows), and MSVC toolchain (msvc). This affects calling conventions, linking, and debug info (like PDB files)
