Trait Implementations

impl Archive for Operation

where GraphQuery: Archive, Mutation: Archive, MutationBatch: Archive, Subscription: Archive, u64: Archive, AggregateQuery: Archive, StreamChangesRequest: Archive,

type Archived = ArchivedOperation

The archived representation of this type.

type Resolver = OperationResolver

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 Operation

fn clone(&self) -> Operation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Operation

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<Operation, __D> for Archived<Operation>

where GraphQuery: Archive, <GraphQuery as Archive>::Archived: Deserialize<GraphQuery, __D>, Mutation: Archive, <Mutation as Archive>::Archived: Deserialize<Mutation, __D>, MutationBatch: Archive, <MutationBatch as Archive>::Archived: Deserialize<MutationBatch, __D>, Subscription: Archive, <Subscription as Archive>::Archived: Deserialize<Subscription, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, AggregateQuery: Archive, <AggregateQuery as Archive>::Archived: Deserialize<AggregateQuery, __D>, StreamChangesRequest: Archive, <StreamChangesRequest as Archive>::Archived: Deserialize<StreamChangesRequest, __D>,

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

Deserializes using the given deserializer

impl PartialEq for Operation

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

where GraphQuery: Serialize<__S>, Mutation: Serialize<__S>, MutationBatch: Serialize<__S>, Subscription: Serialize<__S>, u64: Serialize<__S>, AggregateQuery: Serialize<__S>, StreamChangesRequest: 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 Operation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
