Module os 

Operating-system detection and metadata.

OsInfo captures the host platform’s family, kind, distro (Linux only), version, architecture, byte order, and memory page size. It is probed once on first access and cached for the lifetime of the process.

let os = fsys::os::info();
assert!(!os.version.is_empty());

// Compile-time predicates short-circuit to the active target_os.
if fsys::os::is_linux() {
    assert_eq!(fsys::os::name(), "linux");
}
