[−][src]Struct juniper_iron::GraphQLHandler

pub struct GraphQLHandler<'a, CtxFactory, Query, Mutation, Subscription, CtxT, S = DefaultScalarValue> where
    S: ScalarValue,
    CtxFactory: Fn(&mut Request<'_, '_>) -> IronResult<CtxT> + Send + Sync + 'static,
    CtxT: 'static,
    Query: GraphQLType<S, Context = CtxT> + Send + Sync + 'static,
    Mutation: GraphQLType<S, Context = CtxT> + Send + Sync + 'static,
    Subscription: GraphQLType<S, Context = CtxT> + Send + Sync + 'static,  { /* fields omitted */ }

Handler that executes GraphQL queries in the given schema

The handler responds to GET requests and POST requests only. In GET requests, the query should be supplied in the query URL parameter, e.g. http://localhost:3000/graphql?query={hero{name}}.

POST requests support both queries and variables. POST a JSON document to this endpoint containing the field "query" and optionally "variables". The variables should be a JSON object containing the variable to value mapping.

Implementations

impl<'a, CtxFactory, Query, Mutation, Subscription, CtxT, S> GraphQLHandler<'a, CtxFactory, Query, Mutation, Subscription, CtxT, S> where
    S: ScalarValue + Send + Sync + 'static,
    CtxFactory: Fn(&mut Request<'_, '_>) -> IronResult<CtxT> + Send + Sync + 'static,

    Mutation: GraphQLType<S, Context = CtxT, TypeInfo = ()> + Send + Sync + 'static,
    Subscription: GraphQLType<S, Context = CtxT, TypeInfo = ()> + Send + Sync + 'static, [src]

pub fn new(
    context_factory: CtxFactory,
    query: Query,
    mutation: Mutation,
    subscription: Subscription
) -> Self[src]

Build a new GraphQL handler

The context factory will receive the Iron request object and is expected to construct a context object for the given schema. This can be used to construct e.g. database connections or similar data that the schema needs to execute the query.
