Struct DatagramIpSpecificSocketOptions

pub struct DatagramIpSpecificSocketOptions<I: IpExt, D: WeakDeviceIdentifier> {
    pub hop_limits: SocketHopLimits<I>,
    pub multicast_interface: Option<D>,
    pub multicast_loop: bool,
    pub allow_broadcast: Option<I::BroadcastMarker>,
    pub dscp_and_ecn: DscpAndEcn,
}

A datagram socket’s options.

These options are held twice by dual stack sockets, since they hold different values per IP version.

Fields

hop_limits: SocketHopLimits<I>

The configured hop limits.

multicast_interface: Option<D>

The selected multicast interface.

multicast_loop: bool

Whether multicast packet loopback is enabled or not (see IP_MULTICAST_LOOP flag). Enabled by default.

allow_broadcast: Option<I::BroadcastMarker>

Set to Some when the socket can be used to send broadcast packets.

dscp_and_ecn: DscpAndEcn

IPV6_TCLASS or IP_TOS option.

Trait Implementations

impl<I: IpExt, D: WeakDeviceIdentifier> Clone for DatagramIpSpecificSocketOptions<I, D>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I, D> Debug for DatagramIpSpecificSocketOptions<I, D>

where I: Debug + IpExt, D: Debug + WeakDeviceIdentifier,

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

Formats the value using the given formatter.

impl<I: IpExt, D: WeakDeviceIdentifier> Default for DatagramIpSpecificSocketOptions<I, D>

fn default() -> Self

Returns the “default value” for a type.

impl<I: IpExt, D: WeakDeviceIdentifier, IpType> GenericOverIp<IpType> for DatagramIpSpecificSocketOptions<I, D>

where IpType: IpExt + Ip,

type Type = DatagramIpSpecificSocketOptions<IpType, D>

The type of Self when its IP-generic parameter is replaced with the type NewIp.

impl<I: IpExt, D: WeakDeviceIdentifier> SendOptions<I> for DatagramIpSpecificSocketOptions<I, D>

fn hop_limit(&self, destination: &SpecifiedAddr<I::Addr>) -> Option<NonZeroU8>

Returns the hop limit to set on a packet going to the given destination.

fn multicast_loop(&self) -> bool

Returns true if outgoing multicast packets should be looped back and delivered to local receivers who joined the multicast group.

fn allow_broadcast(&self) -> Option<I::BroadcastMarker>

Some if the socket can be used to send broadcast packets.

fn dscp_and_ecn(&self) -> DscpAndEcn

Returns TCLASS/TOS field value that should be set in IP headers.

fn mtu(&self) -> Mtu

The IP MTU to use for this transmission.
