# `Linx.Netlink.Rtnl.Monitor.Event`
[🔗](https://github.com/oshlabs/linx/blob/v0.2.0/lib/linx/netlink/rtnl/monitor/event.ex#L1)

A single rtnetlink multicast notification decoded by
`Linx.Netlink.Rtnl.Monitor`.

  * `:op` — what happened, as `{new,del}_{link,addr,route,neigh,rule}`, or
    `{:unknown, type}` for an `RTM_*` type the Monitor doesn't decode.
  * `:resource` — the decoded struct (`%Link{}`, `%Address{}`, …) for a known
    op, or `nil` for `{:unknown, _}`.

Events are **wake-up hints**, not authoritative deltas: the netlink multicast
stream is lossy (see the Monitor's `:resync_needed`), so a level-triggered
consumer re-reads and re-diffs full state on any event rather than acting on
the event's contents. The decoded `:resource` is for observability and
filtering.

# `op`

```elixir
@type op() ::
  :new_link
  | :del_link
  | :new_addr
  | :del_addr
  | :new_route
  | :del_route
  | :new_neigh
  | :del_neigh
  | :new_rule
  | :del_rule
  | {:unknown, non_neg_integer()}
```

# `t`

```elixir
@type t() :: %Linx.Netlink.Rtnl.Monitor.Event{op: op(), resource: struct() | nil}
```
