Struct cynic::Operation

pub struct Operation<QueryFragment, Variables = ()> {
    pub query: String,
    pub variables: Variables,
    pub operation_name: Option<Cow<'static, str>>,
    /* private fields */
}

An Operation that can be sent to a remote GraphQL server.

This contains a GraphQL query string and variable HashMap. It can be serialized into JSON with serde::Serialize and sent to a remote server.

Fields

query: String

The graphql query string that will be sent to the server

variables: Variables

The variables that will be sent to the server as part of this operation

operation_name: Option<Cow<'static, str>>

The name of the operation in query that we should run

Implementations

impl<Fragment, Variables> Operation<Fragment, Variables>where Fragment: QueryFragment, Variables: QueryVariables,

pub fn new(query: String, variables: Variables) -> Self

Constructs a new operation from a String & some variables.

This is useful for certain testing cirumstances, but offers no typesafety. crate::QueryBuilder, crate::MutationBuilder and crate::SubscriptionBuilder should be preferered.

pub fn query(variables: Variables) -> Selfwhere Fragment::SchemaType: QueryRoot,

Constructs a new Operation for a query

pub fn mutation(variables: Variables) -> Selfwhere Fragment::SchemaType: MutationRoot,

Constructs a new Operation for a mutation

Trait Implementations

impl<QueryFragment, Variables> Serialize for Operation<QueryFragment, Variables>where Variables: Serialize,

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.
