Struct Sporadic 

pub struct Sporadic {
    pub min_inter_arrival: Duration,
    pub jitter: Duration,
}

The classic sporadic arrival model (originally due to Mok) with release jitter.

A note on terminology: following standard convention, the arrival time of a job denotes the time at which (conceptually) the job is triggered, whereas its release time is the time at which it actually becomes ready for execution.

Fields

min_inter_arrival: Duration

The minimum inter-arrival separation between any two job arrivals of the task.

jitter: Duration

The maximum release jitter, i.e., the maximum time between the arrival and the release of a job.

Implementations

impl Sporadic

pub fn new(min_inter_arrival: Duration, jitter: Duration) -> Sporadic

Construct a new sporadic arrival model with the given inter-arrival time and jitter.

pub fn new_zero_jitter(min_inter_arrival: Duration) -> Sporadic

Construct a new sporadic arrival model with the given inter-arrival time and no jitter.

Trait Implementations

impl ArrivalBound for Sporadic

fn number_arrivals(&self, delta: Duration) -> usize

Bound the number of jobs released in any interval of length delta.

fn steps_iter<'a>(&'a self) -> Box<dyn Iterator<Item = Duration> + 'a>

Yield the sequence of interval lengths (i.e., values of delta in ArrivalBound::number_arrivals) for which the arrival bound “steps”, i.e., where it shows an increase in the number of released jobs.

fn clone_with_jitter(&self, added_jitter: Duration) -> Box<dyn ArrivalBound>

Clone the arrival model while accounting for added release jitter. Returns a boxed dyn object because the underlying type may change.

fn brute_force_steps_iter<'a>( &'a self, ) -> Box<dyn Iterator<Item = Duration> + 'a>

Same semantics as ArrivalBound::steps_iter, but provided by a default implementation in the most naive way possible. Avoid if performance is at all important.

impl Clone for Sporadic

fn clone(&self) -> Sporadic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sporadic

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

Formats the value using the given formatter.

impl From<Periodic> for Sporadic

fn from(p: Periodic) -> Self

Converts to this type from the input type.

impl From<Sporadic> for Curve

fn from(s: Sporadic) -> Self

Converts to this type from the input type.
