Struct net_types::MulticastAddr

pub struct MulticastAddr<A>(/* private fields */);

An address which is guaranteed to be multicast.

MulticastAddr wraps an address of type A and guarantees that it is a multicast address. Note that this guarantee is contingent on a correct implementation of the MulticastAddress trait. Since that trait is not unsafe, unsafe code may NOT rely on this guarantee for its soundness.

Implementations

impl<A: MulticastAddress> MulticastAddr<A>

pub fn new(addr: A) -> Option<MulticastAddr<A>>

Constructs a new MulticastAddr.

new returns None if !addr.is_multicast().

pub fn from_witness<W: Witness<A>>(addr: W) -> Option<MulticastAddr<A>>

Constructs a new MulticastAddr from a witness type.

from_witness(witness) is equivalent to new(witness.into_addr()).

impl<A> MulticastAddr<A>

pub const unsafe fn new_unchecked(addr: A) -> MulticastAddr<A>

Constructs a new MulticastAddr without checking to see if addr is actually multicast.

Safety

It is up to the caller to make sure that addr is multicast to avoid breaking the guarantees of MulticastAddr. See MulticastAddr for more details.

impl<A: MulticastAddress + SpecifiedAddress> MulticastAddr<A>

pub fn into_specified(self) -> SpecifiedAddr<A>

Converts this MulticastAddr into a SpecifiedAddr.

MulticastAddress::is_multicast implies SpecifiedAddress::is_specified, so all MulticastAddrs are guaranteed to be specified, so this conversion is infallible.

impl<A: MulticastAddress + LinkLocalAddress> MulticastAddr<LinkLocalAddr<A>>

pub fn new_link_local(addr: A) -> Option<MulticastAddr<LinkLocalAddr<A>>>

Constructs a new MulticastAddr<LinkLocalAddr<A>>.

new_link_local(addr) is equivalent to LinkLocalAddr::new(addr).and_then(MulticastAddr::new)).

impl<A: MulticastAddress + MappedAddress> MulticastAddr<NonMappedAddr<A>>

pub fn new_non_mapped(addr: A) -> Option<MulticastAddr<NonMappedAddr<A>>>

Constructs a new MulticastAddr<NonMappedAddr<A>>.

new_non_mapped(addr) is equivalent to NonMappedAddr::new(addr).and_then(MulticastAddr::new)).

impl<A: MulticastAddress + MappedAddress> MulticastAddr<A>

pub fn non_mapped(self) -> NonMappedAddr<MulticastAddr<A>>

Wraps self in the NonMappedAddr witness type.
