Macro extract_struct_fields 

macro_rules! extract_struct_fields {
    ($detail:expr, $source:expr, {
        $($key:literal => $field:ident),* $(,)?
    }) => { ... };
}

Extract fields from a struct and insert them into a HashMap. Useful for populating detail HashMaps from device structs. Optimized to avoid redundant allocations for static strings.

Example usage:

extract_struct_fields!(detail, device, {
    "serial_number" => device_sn,
    "firmware_version" => firmware,
    "pci_bdf" => pci_bdf
});
