Enum mz_compute_types::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, types: Option<Vec<ColumnType>>) -> AvailableCollections

Reports all keys of produced arrangements, with optionally given types describing the rows that would be in the raw form of the collection.

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>, Vec<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 Ord for ThresholdPlan

fn cmp(&self, other: &ThresholdPlan) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ThresholdPlan

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

impl PartialOrd for ThresholdPlan

fn partial_cmp(&self, other: &ThresholdPlan) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

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.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

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.
