Struct Time 

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

A point in time, measured as an offset from the start of a run.

Monotonic by construction: the simulator only ever advances it, and a real driver derives it from a base instant captured at startup. Arithmetic saturates rather than wrapping, so monotonicity cannot be broken by overflow.

Implementations

impl Time

pub const ZERO: Time

The start of a run.

pub const MAX: Time

The latest representable time — around 584 billion years in, so useful as a “no deadline” sentinel and unreachable in practice.

pub const fn from_offset(offset: Duration) -> Self

A time offset after the start of the run.

pub const fn from_nanos(nanos: u64) -> Self

pub const fn from_micros(micros: u64) -> Self

pub const fn from_millis(millis: u64) -> Self

pub const fn from_secs(secs: u64) -> Self

pub const fn as_offset(self) -> Duration

The offset from the start of the run.

pub const fn as_nanos(self) -> u128

Nanoseconds since the start of the run. u128, because the range exceeds u64.

pub const fn as_millis(self) -> u128

Milliseconds since the start of the run, truncated.

pub fn saturating_since(self, earlier: Time) -> Duration

Time elapsed from earlier to self, saturating at zero if earlier is later.

pub fn saturating_add(self, d: Duration) -> Time

self advanced by d, saturating at Time::MAX.

Trait Implementations

impl Add<Duration> for Time

type Output = Time

The resulting type after applying the + operator.

fn add(self, d: Duration) -> Time

Performs the + operation.

impl AddAssign<Duration> for Time

fn add_assign(&mut self, d: Duration)

Performs the += operation.

impl Clone for Time

fn clone(&self) -> Time

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Time

impl Debug for Time

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

Formats the value using the given formatter.

impl Default for Time

fn default() -> Time

Returns the “default value” for a type.

impl Eq for Time

impl Hash for Time

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

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 Time

fn cmp(&self, other: &Time) -> 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 Time

fn eq(&self, other: &Time) -> 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 Time

fn partial_cmp(&self, other: &Time) -> 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 StructuralPartialEq for Time

impl Sub for Time

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, earlier: Time) -> Duration

Performs the - operation.
