Expand description

Addresses that can be multicast.

MulticastAddress is implemented by address types for which some values are considered multicast addresses. Multicast addresses are used to identify a group of multiple network nodes, as opposed to unicast addresses, which identify a single node, or broadcast addresses, which identify all the nodes in some region of a network.

Required Methods§

source

fn is_multicast(&self) -> bool

Is this a multicast address?

is_multicast must maintain the invariant that, if it is called twice on the same object, and in between those two calls, no code has operated on a mutable reference to that object, both calls will return the same value. This property is required in order to implement MulticastAddr. Note that, since this is not an unsafe trait, unsafe code may NOT rely on this property for its soundness. However, code MAY rely on this property for its correctness.

If this type also implements SpecifiedAddress, then a.is_multicast() implies a.is_specified().

Provided Methods§

source

fn is_non_multicast(&self) -> bool

Is this a non-multicast address? The inverse of is_multicast().
