Struct VirtualTime 

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

The current time of a virtual clock, shared between the host and whoever moves it.

Cloning shares the same counter: advancing one handle advances every clone, including the one already given to a Clock. The counter is synchronized because a host is reachable from every task of a run, so two tasks may read or advance this clock at the same time.

Implementations

impl VirtualTime

pub fn new() -> Self

A clock sitting at its origin.

pub fn nanos(&self) -> i64

Nanoseconds since the origin.

pub fn advance(&self, nanos: i64)

Moves time forward by nanos.

A monotonic clock never runs backwards, so a negative nanos moves nothing. Time saturates at i64::MAX rather than overflowing, since a clock that wrapped would report a time before one it already reported.

Trait Implementations

impl Clone for VirtualTime

fn clone(&self) -> VirtualTime

Performs copy-assignment from source.

impl Debug for VirtualTime

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

Formats the value using the given formatter.

impl Default for VirtualTime

fn default() -> VirtualTime

Returns the “default value” for a type.
