Struct Filter 

pub struct Filter {
    pub expression: FilterExpr,
}

A filter condition wrapper.

Fields

expression: FilterExpr

The filter expression.

Implementations

impl Filter

pub fn new(expression: FilterExpr) -> Self

Create a filter from an expression.

Trait Implementations

impl Archive for Filter

where FilterExpr: Archive,

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.

type Archived = ArchivedFilter

The archived representation of this type.

type Resolver = FilterResolver

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::Resolver, out: Place<Self::Archived>)

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

impl Clone for Filter

fn clone(&self) -> Filter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Filter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Filter

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<Filter, __D> for Archived<Filter>

where FilterExpr: Archive, <FilterExpr as Archive>::Archived: Deserialize<FilterExpr, __D>,

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

Deserializes using the given deserializer

impl From<FilterExpr> for Filter

fn from(expression: FilterExpr) -> Self

Converts to this type from the input type.

impl PartialEq for Filter

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

where FilterExpr: 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 Filter

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
