Enum TcpOption

pub enum TcpOption<'a> {
    Mss(u16),
    WindowScale(u8),
    SackPermitted,
    Sack(&'a [TcpSackBlock]),
    Timestamp {
        ts_val: u32,
        ts_echo_reply: u32,
    },
}

A TCP header option.

A TCP header option comprises an option kind byte, a length, and the option data itself.

See Wikipedia or RFC 793 for more details.

Variants

Mss(u16)

A Maximum Segment Size (MSS) option.

WindowScale(u8)

A window scale option.

SackPermitted

A selective ACK permitted option.

Sack(&'a [TcpSackBlock])

A selective ACK option.

A variable-length number of selective ACK blocks. The length is in the range [0, 4].

Timestamp

A timestamp option.

Fields

ts_val: u32

ts_echo_reply: u32

Trait Implementations

impl<'a> Clone for TcpOption<'a>

fn clone(&self) -> TcpOption<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TcpOption<'a>

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

Formats the value using the given formatter.

impl<'a> OptionBuilder for TcpOption<'a>

type Layout = TcpOptionsImpl

Information about the option’s layout.

fn serialized_len(&self) -> usize

Returns the serialized length, in bytes, of self.

fn option_kind(&self) -> u8

Returns the wire value for this option kind.

fn serialize_into(&self, buffer: &mut [u8])

Serializes self into data.

impl<'a> PartialEq for TcpOption<'a>

fn eq(&self, other: &TcpOption<'a>) -> 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.
