Enum 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

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

Fields

option_id: u8

expected_len: u8

actual_len: usize

UnexpectedSize

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

Fields

option_id: u8

size: u8

UnknownId(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 duplicate 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)>

Returns 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 PartialEq for TcpOptionReadError

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

Tests for self and other values to be equal, and is used by ==.

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

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