Implementations

impl<I> Lifetime<I>

where I: Instant,

pub fn from_ndp(now: I, duration: NonZeroNdpLifetime) -> Lifetime<I>

Creates a new Lifetime duration from now, saturating to Infinite.

pub fn after(now: I, duration: Duration) -> Lifetime<I>

Creates a new Lifetime duration from now, saturating to Infinite.

impl<Instant> Lifetime<Instant>

pub fn map_instant<N, F>(self, f: F) -> Lifetime<N>

where F: FnOnce(Instant) -> N,

Maps the instant value in this Lifetime with f.

Trait Implementations

impl<I> Clone for Lifetime<I>

where I: Clone,

fn clone(&self) -> Lifetime<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for Lifetime<I>

where I: Debug,

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

Formats the value using the given formatter.

impl<I> Hash for Lifetime<I>

where I: Hash,

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<I> InspectableValue for Lifetime<I>

where I: Instant,

fn record<N>(&self, name: &str, inspector: &mut N)

where N: Inspector,

Records this value into inspector.

impl<I> Ord for Lifetime<I>

where I: Ord,

fn cmp(&self, other: &Lifetime<I>) -> 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<I> PartialEq for Lifetime<I>

where I: PartialEq,

fn eq(&self, other: &Lifetime<I>) -> 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<I> PartialOrd for Lifetime<I>

where I: PartialOrd,

fn partial_cmp(&self, other: &Lifetime<I>) -> 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<I> Copy for Lifetime<I>

where I: Copy,

impl<I> Eq for Lifetime<I>

where I: Eq,

impl<I> StructuralPartialEq for Lifetime<I>
