Struct retina_core::protocols::packet::ethernet::Ethernet

pub struct Ethernet<'a> { /* private fields */ }

An Ethernet frame.

On networks that support virtual LANs, the frame may include a VLAN tag after the source MAC address. Double-tagged frames (QinQ) are not yet supported.

Implementations

impl<'a> Ethernet<'a>

pub fn dst(&self) -> MacAddr

Returns the destination MAC address.

pub fn src(&self) -> MacAddr

Returns the source MAC address.

pub fn ether_type(&self) -> u16

Returns the encapsulated protocol identifier for untagged and single-tagged frames, and 0 for incorrectly fornatted and (not yet supported) double-tagged frames,.

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

Returns the Tag Control Information field from a 802.1Q (single-tagged) frame, if available.

Trait Implementations

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

Formats the value using the given formatter.
