Struct Entry

pub struct Entry {
    pub interface: Option<u64>,
    pub neighbor: Option<IpAddress>,
    pub state: Option<EntryState>,
    pub mac: Option<MacAddress>,
    pub updated_at: Option<i64>,
    /* private fields */
}

Information on a neighboring device in the local network.

There are two types of entries available in the neighbor table.

1. Dynamic entries are discovered automatically by neighbor discovery protocols (e.g. ARP, NDP). These protocols will attempt to reconfirm reachability with the device once its state becomes [EntryState.STALE].
2. Static entries are explicitly added by a user with [Controller.AddEntry] and have no expiration. Their state is always [EntryState.STATIC].

Fields

interface: Option<u64>

Identifier for the interface used for communicating with the neighbor.

Required.

neighbor: Option<IpAddress>

IP address of the neighbor.

Required.

state: Option<EntryState>

State of the entry within the Neighbor Unreachability Detection (NUD) state machine.

Modeled after RFC 4861 section 7.3.2. Descriptions are kept implementation-independent by using a set of generic terminology.

,——————————————————————. | Generic Term | ARP Term | NDP Term | |—————————+———––+————————| | Reachability Probe | ARP Request | Neighbor Solicitation | | Reachability Confirmation | ARP Reply | Neighbor Advertisement | `—————————+———––+————————’

Required.

mac: Option<MacAddress>

MAC address of the neighboring device’s network interface controller.

May be absent for dynamic entries in [EntryState.UNREACHABLE] or [EntryState.INCOMPLETE].

updated_at: Option<i64>

Timestamp when this entry has changed state.

Required.

Trait Implementations

impl Clone for Entry

fn clone(&self) -> Entry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Entry

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<Entry, D> for Entry

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for Entry

fn default() -> Entry

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<Entry, D> for &Entry

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for Entry

fn eq(&self, other: &Entry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeMarker for Entry

type Owned = Entry

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for Entry

type Borrowed<'a> = &'a Entry

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.

impl Persistable for Entry

impl StructuralPartialEq for Entry
