Struct OptionWatchEntry

pub struct OptionWatchEntry {
    pub interface_id: Option<u64>,
    pub source_address: Option<Ipv6Address>,
    pub option_type: Option<u8>,
    pub body: Option<Vec<u8>>,
    /* private fields */
}

An entry representing a single option received in an NDP message.

The option_type and body are not guaranteed to be validated in any way other than the body conforming to length requirements as specified in RFC 4861 section 4.6.

Fields

interface_id: Option<u64>

The interface on which the NDP message containing the option was received.

Always present.

source_address: Option<Ipv6Address>

The source address of the IPv6 packet containing the NDP message in which the option was received.

Always present.

option_type: Option<u8>

The NDP option type.

Always present.

body: Option<Vec<u8>>

The body of the NDP option.

The raw bytes of the NDP option excluding the leading two bytes for the type and the length according to RFC 4861 section 4.6. The body is padded such that if it were prepended with a type octet and a length octet to match the format described in RFC 4861 section 4.6, its length would be a multiple of 8 octets (as required by the RFC).

Always present.

Trait Implementations

impl Clone for OptionWatchEntry

fn clone(&self) -> OptionWatchEntry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OptionWatchEntry

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

Formats the value using the given formatter.

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

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 OptionWatchEntry

fn default() -> OptionWatchEntry

Returns the “default value” for a type.

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

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 OptionWatchEntry

fn eq(&self, other: &OptionWatchEntry) -> 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 OptionWatchEntry

type Owned = OptionWatchEntry

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 OptionWatchEntry

type Borrowed<'a> = &'a OptionWatchEntry

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.
