Implementations

impl TcpOptionKind

pub fn from_byte(b: u8) -> Self

Create from raw option kind byte.

pub fn to_byte(self) -> u8

Convert to raw option kind byte.

pub fn name(&self) -> &'static str

Get the name of the option.

pub fn is_single_byte(&self) -> bool

Check if this is a single-byte option (no length/data).

pub fn expected_len(&self) -> Option<usize>

Get the expected fixed length for this option (if any). Returns None for variable-length options.

Trait Implementations

impl Clone for TcpOptionKind

fn clone(&self) -> TcpOptionKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TcpOptionKind

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

Formats the value using the given formatter.

impl Display for TcpOptionKind

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

Formats the value using the given formatter.

impl PartialEq for TcpOptionKind

fn eq(&self, other: &TcpOptionKind) -> 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.
