fn source_interval( &self, interval: impl QuotedWithContext<'a, Duration, Self> + Copy + 'a, _nondet: NonDet, ) -> Stream<Instant, Self, Unbounded, TotalOrder, ExactlyOnce>

where Self: Sized + NoTick,

Generates a stream with values emitted at a fixed interval, with each value being the current time (as an [tokio::time::Instant]).

The clock source used is monotonic, so elements will be emitted in increasing order.

Non-Determinism

Because this stream is generated by an OS timer, it will be non-deterministic because each timestamp will be arbitrary.

fn source_interval_delayed( &self, delay: impl QuotedWithContext<'a, Duration, Self> + Copy + 'a, interval: impl QuotedWithContext<'a, Duration, Self> + Copy + 'a, _nondet: NonDet, ) -> Stream<Instant, Self, Unbounded, TotalOrder, ExactlyOnce>

where Self: Sized + NoTick,

Generates a stream with values emitted at a fixed interval (with an initial delay), with each value being the current time (as an [tokio::time::Instant]).

The clock source used is monotonic, so elements will be emitted in increasing order.

Non-Determinism

Because this stream is generated by an OS timer, it will be non-deterministic because each timestamp will be arbitrary.

fn forward_ref<S>(&self) -> (ForwardRef<'a, S>, S)

where S: CycleCollection<'a, ForwardRefMarker, Location = Self>, Self: NoTick,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
