Struct mz_compute_types::plan::threshold::RetractionsThresholdPlan

pub struct RetractionsThresholdPlan {
    pub ensure_arrangement: (Vec<MirScalarExpr>, BTreeMap<usize, usize>, Vec<usize>),
}

A plan to maintain all inputs with negative counts, which are subtracted from the output in order to maintain an equivalent collection compared to BasicThresholdPlan.

Fields

ensure_arrangement: (Vec<MirScalarExpr>, BTreeMap<usize, usize>, Vec<usize>)

Description of how the input has been arranged

Trait Implementations

impl Arbitrary for RetractionsThresholdPlan

type Parameters = ()

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

type Strategy = Map<BoxedStrategy<(Vec<MirScalarExpr>, BTreeMap<usize, usize>, Vec<usize>)>, fn(_: (Vec<MirScalarExpr>, BTreeMap<usize, usize>, Vec<usize>)) -> RetractionsThresholdPlan>

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 RetractionsThresholdPlan

fn clone(&self) -> RetractionsThresholdPlan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RetractionsThresholdPlan

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RetractionsThresholdPlan

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for RetractionsThresholdPlan

fn cmp(&self, other: &RetractionsThresholdPlan) -> 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 RetractionsThresholdPlan

fn eq(&self, other: &RetractionsThresholdPlan) -> 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 RetractionsThresholdPlan

fn partial_cmp(&self, other: &RetractionsThresholdPlan) -> 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 Serialize for RetractionsThresholdPlan

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
