Enum mz_dataflow_types::plan::threshold::ThresholdPlan
source · [−]pub enum ThresholdPlan {
Basic(BasicThresholdPlan),
Retractions(RetractionsThresholdPlan),
}
Expand description
A plan describing how to compute a threshold operation.
Variants
Basic(BasicThresholdPlan)
Basic threshold maintains all positive inputs.
Retractions(RetractionsThresholdPlan)
Retractions threshold maintains all negative inputs.
Implementations
sourceimpl ThresholdPlan
impl ThresholdPlan
sourcepub fn keys(&self) -> AvailableCollections
pub fn keys(&self) -> AvailableCollections
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.
sourceimpl ThresholdPlan
impl ThresholdPlan
sourcepub fn create_from(
arity: usize,
maintain_retractions: bool
) -> (Self, (Vec<MirScalarExpr>, HashMap<usize, usize>, Vec<usize>))
pub fn create_from(
arity: usize,
maintain_retractions: bool
) -> (Self, (Vec<MirScalarExpr>, HashMap<usize, usize>, Vec<usize>))
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.
