Enum CovTarget 

#[non_exhaustive]
pub enum CovTarget {
    Local {
        mac: MacAddr,
    },
    Routed {
        router_mac: MacAddr,
        network: u16,
        address: MacAddr,
    },
}

The device a managed COV subscription goes to: on this network at a MAC, or on another network behind a router.

A device keeps a subscription under the address the request came from (Clause 13.14.2), and its notifications carry that subscription’s process identifier back from the device’s own address (Clauses 13.6.1 and 13.7.1). So a notification belongs to this target when it comes from the same address: the MAC with no source network for a local device, or the source network and station address for a routed one. The router a routed notification came through is not part of the device’s address and isn’t compared.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Local

A device on this network.

Fields

mac: MacAddr

Its MAC address.

Routed

A device on another network, reached through a router on this one.

Fields

router_mac: MacAddr

The MAC of the router the requests go to.

network: u16

The device’s network number, 1 to 65534.

address: MacAddr

The device’s MAC address on that network.

Implementations

impl CovTarget

pub fn local(mac: &[u8]) -> Self

A device on this network at mac.

pub fn routed(router_mac: &[u8], network: u16, address: &[u8]) -> Self

A device at address on network, reached through the router at router_mac.

pub fn of_device(device: &DiscoveredDevice) -> Self

Where a discovered device is: routed when its I-Am came with a source network and address (through the router it came from), local otherwise.
