Enum PreferredLifetimeInfo

pub enum PreferredLifetimeInfo {
    PreferredUntil(i64),
    Deprecated(Empty),
}

Information about the preferred lifetime of an IP address or delegated prefix.

Variants

PreferredUntil(i64)

The end of the preferred lifetime.

The address/prefix should not be considered deprecated if zx.Time is in the past. preferred_until is exchanged as a means to inform the deadline where deprecation is expected to happen.

The preferred lifetime of addresses is defined in RFC 4862, section 2.

Addresses configured using a delegated prefix must have a preferred lifetime no longer than that of the prefix according to RFC 8415, section 6.3.

Must be greater than 0. If zx.Time.INFINITE, the preferred lifetime does not expire.

Deprecated(Empty)

The address/prefix is deprecated.

Deprecated addresses should no longer be used for initiating new connections unless explicitly requested, or if no other non-deprecated addresses are assigned (as described in RFC 4862, section 1).

Addresses configured using a deprecated delegated prefix must also be deprecated according to RFC 8415, section 6.3.

An address/prefix can become undeprecated if its preferred lifetime is extended.

Implementations

impl PreferredLifetimeInfo

pub fn ordinal(&self) -> u64

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict unions should not use is_unknown

Trait Implementations

impl Clone for PreferredLifetimeInfo

fn clone(&self) -> PreferredLifetimeInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PreferredLifetimeInfo

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

Formats the value using the given formatter.

impl<D> Decode<PreferredLifetimeInfo, D> for PreferredLifetimeInfo

where D: ResourceDialect,

fn new_empty() -> PreferredLifetimeInfo

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<(), Error>

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

impl<D> Encode<PreferredLifetimeInfo, D> for &PreferredLifetimeInfo

where D: ResourceDialect,

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

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

impl Hash for PreferredLifetimeInfo

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

where __H: Hasher,

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 PreferredLifetimeInfo

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PreferredLifetimeInfo

fn eq(&self, other: &PreferredLifetimeInfo) -> 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 PartialOrd for PreferredLifetimeInfo

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl TypeMarker for PreferredLifetimeInfo

type Owned = PreferredLifetimeInfo

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 PreferredLifetimeInfo

type Borrowed<'a> = &'a PreferredLifetimeInfo

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: &<PreferredLifetimeInfo as TypeMarker>::Owned, ) -> <PreferredLifetimeInfo as ValueTypeMarker>::Borrowed<'_>

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