Different kinds of options that can be present in the options part of a tcp header.

Variants

Noop

“No-Operation” option.

Description from RFC 793:

This option code may be used between options, for example, to align the beginning of a subsequent option on a word boundary. There is no guarantee that senders will use this option, so receivers must be prepared to process options even if they do not begin on a word boundary.

MaximumSegmentSize(u16)

“Maximum Segment Size” option.

Description from RFC 793:

If this option is present, then it communicates the maximum receive segment size at the TCP which sends this segment. This field must only be sent in the initial connection request (i.e., in segments with the SYN control bit set). If this

WindowScale(u8)

SelectiveAcknowledgementPermitted

SelectiveAcknowledgement((u32, u32), [Option<(u32, u32)>; 3])

Timestamp(u32, u32)

Timestamp & echo (first number is the sender timestamp, the second the echo timestamp)

Trait Implementations

impl Clone for TcpOptionElement

fn clone(&self) -> TcpOptionElement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TcpOptionElement

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

Formats the value using the given formatter.

impl PartialEq<TcpOptionElement> for TcpOptionElement

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

This method tests for self and other values to be equal, and is used by ==.

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

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