Enum PreferredLifetime

pub enum PreferredLifetime<Instant> {
    Preferred(Lifetime<Instant>),
    Deprecated,
}

An address’ preferred lifetime information.

Variants

Preferred(Lifetime<Instant>)

Address is preferred. It can be used for new connections.

Lifetime indicates until when the address is expected to remain in preferred state.

Deprecated

Address is deprecated, it should not be used for new connections.

Implementations

impl<Instant> PreferredLifetime<Instant>

pub const fn preferred_until(instant: Instant) -> Self

pub const fn preferred_forever() -> Self

Creates a new PreferredLifetime that is preferred with an infinite lifetime.

pub const fn is_deprecated(&self) -> bool

Returns true if the address is deprecated.

pub fn map_instant<N, F: FnOnce(Instant) -> N>( self, f: F, ) -> PreferredLifetime<N>

Maps the instant value in this PreferredLifetime with f.

impl<I: Instant> PreferredLifetime<I>

pub fn preferred_for(now: I, duration: NonZeroNdpLifetime) -> Self

Creates a new PreferredLifetime that is preferred for duration after now.

pub fn maybe_preferred_for(now: I, duration: Option<NonZeroNdpLifetime>) -> Self

Creates a new PreferredLifetime that is preferred for duration after now if it is Some, deprecated otherwise.

Trait Implementations

impl<Instant: Ord> Ord for PreferredLifetime<Instant>

fn cmp(&self, other: &PreferredLifetime<Instant>) -> 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.

impl<Instant: PartialEq> PartialEq for PreferredLifetime<Instant>

fn eq(&self, other: &PreferredLifetime<Instant>) -> bool

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

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