Errors in the given data

Variants

Ipv4OptionsLengthBad(usize)

Tuple Fields

0: usize

Error when the ipv4 options length is too big or not aligned (cannot be bigger then 40 bytes and must be a multiple of 4 bytes).

Ipv4PayloadLengthTooLarge(usize)

Tuple Fields

0: usize

Error when a given payload & ipv4 header is bigger then what fits inside an ipv4 total_length field.

Ipv6PayloadLengthTooLarge(usize)

Tuple Fields

0: usize

Error when a given payload & ipv6 header block is bigger then what fits inside an ipv6 payload_length field.

Ipv6ExtensionPayloadTooSmall(usize)

Tuple Fields

0: usize

Error when a given payload size is smaller then 6 octets which is the minimum ipv6 extended header size (Ipv6RawExtensionHeader::MAX_PAYLOAD_LEN).

Ipv6ExtensionPayloadTooLarge(usize)

Tuple Fields

0: usize

Error when a given payload size is bigger then what fits inside an ipv6 extended header size (Ipv6RawExtensionHeader::MAX_PAYLOAD_LEN).

Ipv6ExtensionPayloadLengthUnaligned(usize)

Tuple Fields

0: usize

Error when a given payload length is not aligned to be a multiple of 8 octets when 6 is substracted and can not be represented by the header length field.

IpAuthenticationHeaderBadIcvLength(usize)

Tuple Fields

0: usize

Error when a given authentication header icv size is not a multiple of 4 bytes or bigger then 1016 bytes and therefor can not be represented in the header length field.

Ipv4ExtensionNotReferenced(IpNumber)

Tuple Fields

0: IpNumber

Error when a header in Ipv4Extensions is never written as it is never referenced by any of the other next_header fields or the initial protocol.

Ipv6ExtensionHopByHopNotAtStart

Error when a hop-by-hop header is not referenced as the first header after the ipv6 header but as a later extension header.

Ipv6ExtensionNotReferenced(IpNumber)

Tuple Fields

0: IpNumber

Error when a header in Ipv6Extensions is never written as it is never referenced by any of the other next_header fields or the initial ip number.

Ipv6ExtensionNotDefinedReference(IpNumber)

Tuple Fields

0: IpNumber

Error when a header in Ipv6Extensions is referenced multiple times or is referenced and not defined.

UdpPayloadLengthTooLarge(usize)

Tuple Fields

0: 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)

Tuple Fields

0: 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

Fields

value: u8

max: u8

field: ErrorField

Error when a u8 field in a header has a larger value then supported.

U16TooLarge

Fields

value: u16

max: u16

field: ErrorField

Error when a u16 field in a header has a larger value then supported.

U32TooLarge

Fields

value: u32

max: u32

field: ErrorField

Error when a u32 field in a header has a larger value then supported.

Trait Implementations

impl Clone for ValueError

fn clone(&self) -> ValueError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ValueError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ValueError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
