Struct web_instant::Spot

pub struct Spot { /* private fields */ }

Implementations

impl Spot

pub fn now() -> Self

pub fn elapsed(&self) -> Duration

Returns the amount of time elapsed since this instant was created.

pub fn duration_since(&self, earlier: Spot) -> Duration

Returns the amount of time elapsed from another instant to this one, or zero duration if that instant is later than this one.

pub fn checked_duration_since(&self, earlier: Spot) -> Option<Duration>

Returns the amount of time elapsed from another instant to this one, or None if that instant is later than this one.

Due to [monotonicity bugs], even under correct logical ordering of the passed Instants, this method can return None.

pub fn saturating_duration_since(&self, earlier: Spot) -> Duration

Returns the amount of time elapsed from another instant to this one, or zero duration if that instant is later than this one.

pub fn checked_add(&self, duration: Duration) -> Option<Spot>

Returns Some(t) where t is the time self + duration if t can be represented as Instant (which means it’s inside the bounds of the underlying data structure), None otherwise.

pub fn checked_sub(&self, duration: Duration) -> Option<Spot>

Returns Some(t) where t is the time self - duration if t can be represented as Instant (which means it’s inside the bounds of the underlying data structure), None otherwise.

Trait Implementations

impl Add<Duration> for Spot

fn add(self, other: Duration) -> Spot

Panics

This function may panic if the resulting point in time cannot be represented by the underlying data structure. See Spot::checked_add for a version without panic.

type Output = Spot

The resulting type after applying the + operator.

impl AddAssign<Duration> for Spot

fn add_assign(&mut self, other: Duration)

Performs the += operation.

impl Clone for Spot

fn clone(&self) -> Spot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Spot

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

Formats the value using the given formatter.

impl PartialEq<Spot> for Spot

fn eq(&self, other: &Spot) -> 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<Spot> for Spot

fn partial_cmp(&self, other: &Spot) -> 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 Sub<Duration> for Spot

type Output = Spot

The resulting type after applying the - operator.

fn sub(self, other: Duration) -> Spot

Performs the - operation.

impl Sub<Spot> for Spot

fn sub(self, other: Spot) -> Duration

Returns the amount of time elapsed from another instant to this one, or zero duration if that instant is later than this one.

type Output = Duration

The resulting type after applying the - operator.

impl SubAssign<Duration> for Spot

fn sub_assign(&mut self, other: Duration)

Performs the -= operation.

impl Copy for Spot

impl StructuralPartialEq for Spot
