Enum etherparse::TcpOptionReadError

pub enum TcpOptionReadError {
    UnexpectedEndOfSlice {
        option_id: u8,
        expected_len: u8,
        actual_len: usize,
    },
    UnexpectedSize {
        option_id: u8,
        size: u8,
    },
    UnknownId(u8),
}

Errors that can occour while reading the options of a TCP header.

Variants

UnexpectedEndOfSlice

Fields

option_id: u8

expected_len: u8

actual_len: usize

Returned if an option id was read, but there was not enough memory in the options left to completely read it.

UnexpectedSize

Fields

option_id: u8

size: u8

Returned if the option as an unexpected size argument (e.g. != 4 for maximum segment size).

UnknownId(u8)

Tuple Fields

0: u8

Returned if an unknown tcp header option is encountered.

The first element is the identifier and the slice contains the rest of data left in the options.

Trait Implementations

impl Clone for TcpOptionReadError

fn clone(&self) -> TcpOptionReadError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TcpOptionReadError

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

Formats the value using the given formatter.

impl Display for TcpOptionReadError

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

Formats the value using the given formatter.

impl Error for TcpOptionReadError

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
