Struct SystemClock 

pub struct SystemClock;

The real OS clock. Native behavior is identical to the direct std/tokio calls it replaces.

Trait Implementations

impl Clock for SystemClock

fn now(&self) -> Instant

Monotonic instant for measuring elapsed time. Never persisted.

fn timestamp_ms(&self) -> u64

Wall-clock time as epoch milliseconds, for durable records.

fn timestamp_rfc3339(&self) -> String

Wall-clock time as an RFC 3339 string, for durable records.

fn timestamp_datetime(&self) -> DateTime<Utc>

Wall-clock time as a UTC datetime, for trace records.

fn sleep<'life0, 'async_trait>( &'life0 self, duration: Duration, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Sleep for duration. Replaces tokio::time::sleep.

fn sleep_until<'life0, 'async_trait>( &'life0 self, deadline: Instant, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Sleep until deadline (a value from now). Replaces tokio::time::sleep_until.

impl Clone for SystemClock

fn clone(&self) -> SystemClock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SystemClock

impl Debug for SystemClock

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

Formats the value using the given formatter.

impl Default for SystemClock

fn default() -> SystemClock

Returns the “default value” for a type.
