Errors in the given data

Variants

Ipv4OptionsLengthBad(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)

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

Ipv6PayloadLengthTooLarge(usize)

Error when a given payload & ipv6 header 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.

Trait Implementations

impl Clone for ValueError

fn clone(&self) -> ValueError

Returns a copy of the value.

pub 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 Eq for ValueError

impl Error for ValueError

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

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

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

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

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<ValueError> for WriteError

fn from(err: ValueError) -> WriteError

Performs the conversion.

impl PartialEq<ValueError> for ValueError

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

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

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

This method tests for !=.
