Enum fidl_fuchsia_net_neighbor::EntryState

#[repr(u32)]
pub enum EntryState {
    Incomplete = 1,
    Reachable = 2,

    Delay = 4,

}

Variants

Incomplete = 1

Reachability is in the process of being confirmed for a newly created, non-static entry.

Reachable = 2

Positive reachability has been confirmed; the path to the neighbor is functioning properly.

Stale = 3

Reachability is considered unknown.

Occurs in one of two ways:

1. Too much time has elapsed since the last positive reachability confirmation was received.
2. Received a reachability confirmation from a neighbor with a different MAC address than the one cached.

Delay = 4

A packet was recently sent while reachability was considered unknown.

This state is an optimization that gives non-Neighbor-Discovery related protocols time to confirm reachability after the last confirmation of reachability has expired due to lack of recent traffic.

Probe = 5

A reachability confirmation is actively sought by periodically retransmitting reachability probes until a reachability confirmation is received, or until the maximum number of probes has been sent.

Static = 6

Static entries are explicitly added with [Controller.AddEntry]. They do not expire and are not deleted until explicitly removed with [Controller.RemoveEntry].

Unreachable = 7

Negative reachability has been confirmed; the path to the neighbor may not be functioning properly. A reachability confirmation was not received after transmitting the maximum number of reachability probes.

Implementations

impl EntryState

pub fn from_primitive(prim: u32) -> Option<Self>

pub const fn into_primitive(self) -> u32

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict enums should not use is_unknown

Trait Implementations

impl Clone for EntryState

fn clone(&self) -> EntryState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntryState

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

Formats the value using the given formatter.

impl Decode<EntryState> for EntryState

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<'_>, offset: usize, _depth: Depth ) -> Result<()>

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

impl Encode<EntryState> for EntryState

unsafe fn encode( self, encoder: &mut Encoder<'_>, 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 Hash for EntryState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for EntryState

fn cmp(&self, other: &EntryState) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for EntryState

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for EntryState

fn partial_cmp(&self, other: &EntryState) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for EntryState

type Owned = EntryState

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 EntryState

type Borrowed<'a> = EntryState

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<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

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