Function boot_order_bytes

dstack-mr/src/uefi_var.rs:17–23

Build the raw bytes of a `BootOrder` UEFI variable from a sequence of boot option numbers — each entry is a little-endian `u16` referring to a `Boot####` variable.

(entries: &[u16])

/// option numbers — each entry is a little-endian `u16` referring to a
/// `Boot####` variable.
pub fn boot_order_bytes(entries: &[u16]) -> Vec<u8> {
    let mut out = Vec::with_capacity(entries.len() * 2);
    for &entry in entries {
        out.extend_from_slice(&entry.to_le_bytes());
    }
    out
}
