    Overview

    Package endian implements a simple translation between bytes and numbers with specific endian encodings.

    buf: [100]u8 put_u16(buf[:], .Little, 16) or_return

    You may ask yourself, why isn't byte_order platform Endianness by default, so we can write: put_u16(buf[:], 16) or_return

    The answer is that very few file formats are written in native/platform endianness. Most of them specify the endianness of each of their fields, or use a header field which specifies it for the entire file.

    e.g. a file which specifies it at the top for all fields could do this: file_order := .Little if buf[0] == 0 else .Big field := get_u16(buf[1:], file_order) or_return

    If on the other hand a field is always Big-Endian, you're wise to explicitly state it for the benefit of the reader, be that your future self or someone else.

    field := get_u16(buf[:], .Big) or_return
