Enum FrameDestination

pub enum FrameDestination {
    Individual {
        local: bool,
    },
    Multicast,
    Broadcast,
}

The type of address used as the destination address in a device-layer frame.

FrameDestination is used to implement RFC 1122 section 3.2.2 and RFC 4443 section 2.4.e, which govern when to avoid sending an ICMP error message for ICMP and ICMPv6 respectively.

Variants

Individual

A unicast address - one which is neither multicast nor broadcast.

Fields

local: bool

Whether the frame’s destination address belongs to the receiver.

Multicast

A multicast address; if the addressing scheme supports overlap between multicast and broadcast, then broadcast addresses should use the Broadcast variant.

Broadcast

A broadcast address; if the addressing scheme supports overlap between multicast and broadcast, then broadcast addresses should use the Broadcast variant.

Implementations

impl FrameDestination

pub fn is_broadcast(self) -> bool

Is this FrameDestination::Broadcast?

pub fn from_dest(destination: Mac, local_mac: Mac) -> Self

Creates a FrameDestination from a mac and local_mac destination.

Trait Implementations

impl Clone for FrameDestination

fn clone(&self) -> FrameDestination

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameDestination

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

Formats the value using the given formatter.

impl From<BroadcastAddr<Mac>> for FrameDestination

fn from(_value: BroadcastAddr<Mac>) -> Self

Converts to this type from the input type.

impl From<MulticastAddr<Mac>> for FrameDestination

fn from(_value: MulticastAddr<Mac>) -> Self

Converts to this type from the input type.

impl PartialEq for FrameDestination

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