Enum mz_compute_client::plan::threshold::ThresholdPlan

pub enum ThresholdPlan {
    Basic(BasicThresholdPlan),
}

A plan describing how to compute a threshold operation.

Variants

Basic(BasicThresholdPlan)

Basic threshold maintains all positive inputs.

Implementations

impl ThresholdPlan

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.

impl ThresholdPlan

pub fn create_from( arity: usize ) -> (Self, (Vec<MirScalarExpr>, BTreeMap<usize, usize>, Vec<usize>))

Construct the plan from the number of columns (arity).

Also returns the arrangement and thinning required for the input.

Trait Implementations

impl Arbitrary for ThresholdPlan

type Parameters = <BasicThresholdPlan as Arbitrary>::Parameters

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<<BasicThresholdPlan as Arbitrary>::Strategy, fn(_: BasicThresholdPlan) -> ThresholdPlan>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for ThresholdPlan

fn clone(&self) -> ThresholdPlan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ThresholdPlan

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ThresholdPlan

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<ThresholdPlan> for ThresholdPlan

fn eq(&self, other: &ThresholdPlan) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RustType<ProtoThresholdPlan> for ThresholdPlan

fn into_proto(&self) -> ProtoThresholdPlan

Convert a Self into a Proto value.

fn from_proto(proto: ProtoThresholdPlan) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

impl Serialize for ThresholdPlan

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
