Implementations

impl TcpOptions

pub fn new() -> Self

Create empty options.

pub fn from_vec(options: Vec<TcpOption>) -> Self

Create from a list of options.

pub fn is_empty(&self) -> bool

Check if there are no options.

pub fn len(&self) -> usize

Get the number of options.

pub fn byte_len(&self) -> usize

Get the total serialized length.

pub fn padded_len(&self) -> usize

Get the padded length (aligned to 4 bytes).

pub fn push(&mut self, option: TcpOption)

Add an option.

pub fn get(&self, kind: TcpOptionKind) -> Option<&TcpOption>

Get an option by kind.

pub fn mss(&self) -> Option<u16>

Get the MSS value if present.

pub fn wscale(&self) -> Option<u8>

Get the Window Scale value if present.

pub fn timestamp(&self) -> Option<TcpTimestamp>

Get the Timestamp if present.

pub fn sack_permitted(&self) -> bool

Check if SACK is permitted.

pub fn sack_blocks(&self) -> Option<&[TcpSackBlock]>

Get the SACK blocks if present.

pub fn ao(&self) -> Option<&TcpAoValue>

Get the Authentication Option if present.

pub fn tfo_cookie(&self) -> Option<&[u8]>

Get the TFO cookie if present.

pub fn to_bytes(&self) -> Vec<u8>

Serialize all options to bytes (with padding).

pub fn to_bytes_unpadded(&self) -> Vec<u8>

Serialize to bytes without padding.

Trait Implementations

impl Clone for TcpOptions

fn clone(&self) -> TcpOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TcpOptions

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

Formats the value using the given formatter.

impl Default for TcpOptions

fn default() -> TcpOptions

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a TcpOptions

type Item = &'a TcpOption

The type of the elements being iterated over.

type IntoIter = Iter<'a, TcpOption>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for TcpOptions

type Item = TcpOption

The type of the elements being iterated over.

type IntoIter = IntoIter<TcpOption>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for TcpOptions

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