Errors in the given data
Variants§
Ipv4OptionsLengthBad(usize)
Error when the ipv4 options length is too big (cannot be bigger then 40 bytes and must be a multiple of 4 bytes).
Ipv4PayloadAndOptionsLengthTooLarge(usize)
Error when a given payload & ipv4 options block is bigger then what fits inside an ipv4 total_length field.
Ipv6PayloadLengthTooLarge(usize)
Error when a given payload & ipv6 header existsns block is bigger then what fits inside an ipv6 payload_length field.
UdpPayloadLengthTooLarge(usize)
Error when a given payload is bigger then what fits inside an udp packet Note that a the maximum payload size, as far as udp is conceirned, is max_value(u16) - 8. The 8 is for the size of the udp header itself.
TcpLengthTooLarge(usize)
Error when a given payload + tcp header options is bigger then what fits inside an tcp packet Note that a the maximum size, as far as tcp is conceirned, is max_value(u16) - tcp_header.data_offset()*4. The data_offset is for the size of the udp header itself.
U8TooLarge
Error when a u8 field in a header has a larger value then supported.
U16TooLarge
Error when a u16 field in a header has a larger value then supported.
U32TooLarge
Error when a u32 field in a header has a larger value then supported.
