Enum dataflow_types::plan::threshold::ThresholdPlan[][src]

pub enum ThresholdPlan {
    Basic(BasicThresholdPlan),
    Retractions(RetractionsThresholdPlan),
}
Expand description

A plan describing how to compute a threshold operation.

Variants

Basic(BasicThresholdPlan)

Tuple Fields

Basic threshold maintains all positive inputs.

Retractions(RetractionsThresholdPlan)

Tuple Fields

Retractions threshold maintains all negative inputs.

Implementations

Reports all keys of produced arrangements.

This is likely either an empty vector, for no arrangement, or a singleton vector containing the list of expressions that key a single arrangement.

Construct the plan from the number of columns (arity). maintain_retractions allows to switch between an implementation that maintains rows with negative counts (true), or rows with positive counts (false).

Also returns the arrangement and thinning required for the input.
