    NotLike {

    },
}

A simple (non-compound) filter for use in And/Or expressions.

This flattens the filter structure to avoid recursion issues with rkyv.

Implementations

impl SimpleFilter

pub fn eq(field: impl Into<String>, value: impl Into<Value>) -> Self

Create an equality filter.

pub fn ne(field: impl Into<String>, value: impl Into<Value>) -> Self

Create a not-equal filter.

pub fn is_null(field: impl Into<String>) -> Self

Create an IS NULL filter.

pub fn is_not_null(field: impl Into<String>) -> Self

Create an IS NOT NULL filter.

Trait Implementations

impl Archive for SimpleFilter

where String: Archive, Value: Archive, Vec<Value>: Archive,

type Archived = ArchivedSimpleFilter

The archived representation of this type.

type Resolver = SimpleFilterResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for SimpleFilter

fn clone(&self) -> SimpleFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleFilter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SimpleFilter

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<SimpleFilter, __D> for Archived<SimpleFilter>

where String: Archive, <String as Archive>::Archived: Deserialize<String, __D>, Value: Archive, <Value as Archive>::Archived: Deserialize<Value, __D>, Vec<Value>: Archive, <Vec<Value> as Archive>::Archived: Deserialize<Vec<Value>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<SimpleFilter, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for SimpleFilter

fn eq(&self, other: &SimpleFilter) -> 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<__S: Fallible + ?Sized> Serialize<__S> for SimpleFilter

where String: Serialize<__S>, Value: Serialize<__S>, Vec<Value>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for SimpleFilter

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
