Struct zng_time::DInstant

pub struct DInstant(/* private fields */);

Duration elapsed since an epoch.

By default this is the duration elapsed since the first usage of INSTANT in the process.

Implementations

impl DInstant

pub fn elapsed(self) -> Duration

Returns the amount of time elapsed since this instant.

pub fn duration_since(self, earlier: DInstant) -> 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<DInstant>

Returns Some(t) where t is the time self + duration if t can be represented.

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

Returns Some(t)`` where t is the time self - durationifduration` greater then the elapsed time since the process start.

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

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

pub fn saturating_duration_since(&self, earlier: DInstant) -> 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 const EPOCH: DInstant = _

Earliest instant.

pub const MAX: DInstant = _

The maximum representable instant.

impl Ord for DInstant

fn cmp(&self, other: &DInstant) -> 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 + PartialOrd,

impl PartialEq for DInstant

fn eq(&self, other: &DInstant) -> 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.

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.
