Implementations

impl TransportProtocol

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

Returns the source port if this is TCP or UDP.

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

Returns the destination port if this is TCP or UDP.

pub fn is_syn(&self) -> bool

Returns true if this is a TCP SYN (connection initiation).

pub fn is_fin(&self) -> bool

Returns true if this is a TCP FIN (connection close).

pub fn is_rst(&self) -> bool

Returns true if this is a TCP RST (connection reset).

pub fn protocol_number(&self) -> u8

Returns the protocol number (6=TCP, 17=UDP, 1=ICMP, 58=ICMPv6).

Trait Implementations

impl Clone for TransportProtocol

fn clone(&self) -> TransportProtocol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransportProtocol

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

Formats the value using the given formatter.

impl PartialEq for TransportProtocol

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