Variants

UnexpectedBufferEnd(UnexpectedBufferEndError)

The data buffer ended unexpectedly.

VersionHeaderValueNotFour

Version header value is not four.

IhlHeaderValueTooSmall

Fields

ihl: usize

Invalid IHL value.

IHL header value is smaller than 5.

PacketShorterThanTotalLengthHeaderValue

Fields

total_length_header: usize

Total length header value.

actual_packet_length: usize

Actual length of the packet.

The packet is shorter than the total length header specifies.

TotalLengthHeaderValueSmallerThanIhlHeaderValue

Fields

total_length_header: usize

Total length header value.

ihl_header_in_bytes: usize

Length specified by the IHL header in bytes (IHL header specifies amount of 32 bit words).

The total length header value is smaller than the packet length specified by the IHL header.

PacketShorterThanIhlHeaderValue

Fields

ihl_header_in_bytes: usize

Length specified by the IHL header in bytes (IHL header specifies amount of 32 bit words).

actual_packet_length: usize

Actual length of the packet.

The packet is shorter than the length specified by the IHL header.

UnrecognizedInternetProtocolNumber(UnrecognizedInternetProtocolNumberError)

Internet protocol number is recognized.

InvalidChecksum(InvalidChecksumError)

Invalid checksum.

Trait Implementations

impl Clone for ParseIpv4Error

fn clone(&self) -> ParseIpv4Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseIpv4Error

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

Formats the value using the given formatter.

impl Display for ParseIpv4Error

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

Formats the value using the given formatter.

impl Error for ParseIpv4Error

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

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

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type based access to context intended for error reports.

impl From<InvalidChecksumError> for ParseIpv4Error

fn from(value: InvalidChecksumError) -> Self

Converts to this type from the input type.

impl From<LengthExceedsAvailableSpaceError> for ParseIpv4Error

fn from(value: LengthExceedsAvailableSpaceError) -> Self

Converts to this type from the input type.

impl From<ParseIpv4Error> for ParseNetworkDataError

fn from(value: ParseIpv4Error) -> Self

Converts to this type from the input type.

impl From<UnexpectedBufferEndError> for ParseIpv4Error

fn from(value: UnexpectedBufferEndError) -> Self

Converts to this type from the input type.

impl From<UnrecognizedInternetProtocolNumberError> for ParseIpv4Error

fn from(value: UnrecognizedInternetProtocolNumberError) -> Self

Converts to this type from the input type.

impl Hash for ParseIpv4Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ParseIpv4Error

fn cmp(&self, other: &ParseIpv4Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for ParseIpv4Error

fn eq(&self, other: &ParseIpv4Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ParseIpv4Error

fn partial_cmp(&self, other: &ParseIpv4Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
