Struct Instant 

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

Typed monotonic timestamp for try_*_until deadlines.

Wraps a nanosecond count from the substrate’s steady clock. Construct only via Instant::now or by adding a Duration to an existing Instant. The internal representation is opaque on purpose: this is what makes a raw u64 of microseconds or relative duration nanoseconds fail to compile when fed to a try_*_until call.

Matches std::time::Instant’s opaque-newtype shape (we can’t use the std type directly because it lives in std, not core — see also parking_lot::Mutex::try_lock_until which takes std Instant on host but the equivalent type on no_std targets).

Examples

use core::time::Duration;
use ove::time::Instant;

let deadline = Instant::now() + Duration::from_millis(100);
mtx.try_lock_until(deadline)?;

// Or wait indefinitely:
mtx.try_lock_until(Instant::FOREVER)?;

Implementations

impl Instant

pub const FOREVER: Instant

Sentinel “wait indefinitely” deadline.

Mapped to the substrate’s OVE_WAIT_FOREVER constant via the internal raw-ns representation. Useful when a function’s signature only exposes a deadline variant but the caller wants to block forever.

pub fn now() -> Self

Returns the current value of the substrate steady clock.

Trait Implementations

impl Add<Duration> for Instant

type Output = Instant

The resulting type after applying the + operator.

fn add(self, rhs: Duration) -> Instant

Performs the + operation.

impl AddAssign<Duration> for Instant

fn add_assign(&mut self, rhs: Duration)

Performs the += operation.

impl Clone for Instant

fn clone(&self) -> Instant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Instant

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

Formats the value using the given formatter.

impl Hash for Instant

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 Instant

fn cmp(&self, other: &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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Instant

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

fn partial_cmp(&self, other: &Instant) -> 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 Sub for Instant

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, rhs: Instant) -> Duration

Performs the - operation.
