Implementations

impl TransportLayer<'_>

pub fn ports(&self) -> (u16, u16)

Extracts the source and destination ports from the transport layer header.

For TCP, UDP, and SCTP headers, returns the actual source and destination ports. For ICMP and ICMPv6 headers, which don’t have port numbers, returns (0, 0).

Returns

A tuple containing (source_port, destination_port). For protocols without port numbers, both values will be 0.

Trait Implementations

impl<'a> Clone for TransportLayer<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TransportLayer<'a>

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

Formats the value using the given formatter.

impl Display for TransportLayer<'_>

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

Formats the value using the given formatter.

impl SourceDestLayer<u16> for TransportLayer<'_>

fn source(&self) -> Option<u16>

Extracts the source port from the transport layer header.

Returns the source port for TCP, UDP, and SCTP headers. Returns None for ICMP and ICMPv6 headers, which don’t have port numbers.

fn dest(&self) -> Option<u16>

Extracts the destination port from the transport layer header.

Returns the destination port for TCP, UDP, and SCTP headers. Returns None for ICMP and ICMPv6 headers, which don’t have port numbers.
