Enum AnytimeStatus 

pub enum AnytimeStatus<Q> {
    Improved(Q),
    Converged(Q),
    Aborted,
}

Returned by CuAnytimeTask::base and CuAnytimeTask::refine; drives the runtime’s refinement scheduling.

Q is CuAnytimeTask::Quality: Quality for tasks that can score their result, () for tasks that cannot.

After any Ok return, the output must be valid and hold the best result produced so far for the current job: a quantum that regresses or plateaus keeps its candidate in task-local state and leaves the output untouched. The runtime never buffers or rolls back the output, so it can publish it at any stop point, and the published quality is monotone even when the algorithm internally is not.

Variants

Improved(Q)

The output holds the best result so far; further refinement may help.

Converged(Q)

Proactive yield: no further improvement is possible for this job. The output holds the final result, published unless the quality floor rejects it.

Aborted

Proactive give-up: the algorithm diverged or reached an unrecoverable state for this job. Refinement stops; the output is published as-is — subject to the quality floor once a quality has been reported — so a task that can no longer vouch even for its base result must clear the payload before returning this. The next copperlist starts a fresh job.

Trait Implementations

impl<Q: Clone> Clone for AnytimeStatus<Q>

fn clone(&self) -> AnytimeStatus<Q>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Q: Copy> Copy for AnytimeStatus<Q>

impl<Q: Debug> Debug for AnytimeStatus<Q>

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

Formats the value using the given formatter.

impl<Q: PartialEq> PartialEq for AnytimeStatus<Q>

fn eq(&self, other: &AnytimeStatus<Q>) -> 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.
