Enum LengthEncoding

Source
pub enum LengthEncoding {
    TypeLengthValue {
        option_len_multiplier: NonZeroUsize,
    },
    ValueOnly,
}
Expand description

Whether the length field of an option encodes the length of the entire option (including kind and length fields) or only of the value field.

For the TypeLengthValue variant, an option_len_multiplier may also be specified. Some formats (such as NDP) do not directly encode the length in bytes of each option, but instead encode a number which must be multiplied by option_len_multiplier in order to get the length in bytes.
