Struct partiql_value::NullSortedValue

pub struct NullSortedValue<'a, const NULLS_FIRST: bool, T>(pub &'a T);

A wrapper on [T] that specifies if a null or missing value should be ordered before ([NULLS_FIRST] is true) or after ([NULLS_FIRST] is false) other values.

Tuple Fields

0: &'a T

Trait Implementations

impl<'a, const NULLS_FIRST: bool> Ord for NullSortedValue<'a, NULLS_FIRST, Bag>

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'a, const NULLS_FIRST: bool> Ord for NullSortedValue<'a, NULLS_FIRST, List>

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

This method returns an Ordering between self and other.

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'a, const NULLS_FIRST: bool> Ord for NullSortedValue<'a, NULLS_FIRST, Tuple>

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'a, const NULLS_FIRST: bool> Ord for NullSortedValue<'a, NULLS_FIRST, Value>

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'a, const NULLS_FIRST: bool, T: PartialEq> PartialEq<NullSortedValue<'a, NULLS_FIRST, T>> for NullSortedValue<'a, NULLS_FIRST, T>

fn eq(&self, other: &NullSortedValue<'a, NULLS_FIRST, T>) -> 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<'a, const NULLS_FIRST: bool, T> PartialOrd<NullSortedValue<'a, NULLS_FIRST, T>> for NullSortedValue<'a, NULLS_FIRST, T>where T: PartialOrd, NullSortedValue<'a, NULLS_FIRST, T>: Ord,

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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