Modules

executor

Resolve the document to values

http

Utilities for building HTTP endpoints in a library-agnostic manner

integrations

Provides GraphQLType implementations for some external types

marker

Marker traits for GraphQL types.

meta

Types used to describe a GraphQL schema

parser

Query parser and language utilities

tests

Library tests and fixtures

validation

Query validation related methods and data structures

Macros

assert_field

Asserts validness of [Field] [Arguments] and returned [Type].

assert_field_args

Asserts validness of the [Field]s arguments. See spec for more info.

assert_implemented_for

Asserts that #[graphql_interface(for = ...)] has all the types referencing this interface in the impl = ... attribute argument.

assert_interfaces_impls

Asserts that impl = ... attribute argument has all the types referencing this GraphQL type in #[graphql_interface(for = ...)].

assert_subtype

Asserts validness of a [Field] return type.

assert_transitive_impls

Asserts that all transitive interfaces (the ones implemented by the $interface) are also implemented by the $implementor.

checked_hash

Ensures that the given $impl_ty implements [Field] and returns a [fnv1a128] hash for it, otherwise panics with understandable message.

const_concat

Concatenates const strs in a const context.

format_type

Formats the given [Type] and [WrappedValue] into a readable GraphQL type name.

graphql_input_value

Constructs InputValues via JSON-like syntax.

graphql_value

Constructs Values via JSON-like syntax.

graphql_vars

Constructs Variables via JSON-like syntax.

Structs

Arguments

Field argument container

EmptyMutation

Utility type to define read-only schemas

EmptySubscription

Utillity type to define read-only schemas

ExecutionOutput

Represents the result of executing a GraphQL operation (after parsing and validating has been done).

ID

An ID as defined by the GraphQL specification

Object

An Object value

Operation

RootNode

Root query node of a schema

SchemaType

Metadata for a schema

Enums

DefaultScalarValue

The default ScalarValue representation in juniper.

GraphQLError

An error that prevented query execution

InputValue

A JSON-like value that can be passed into the query execution, either out-of-band, or in-band as default variable values. These are not constant and might contain variables.

IntrospectionFormat

The desired GraphQL introspection format for the canonical query (https://github.com/graphql/graphql-js/blob/90bd6ff72625173dd39a1f82cfad9336cfad8f65/src/utilities/getIntrospectionQuery.ts#L62)

Nullable

Nullable can be used in situations where you need to distinguish between an implicitly and explicitly null input value.

OperationType

Selection

Entry in a GraphQL selection set

Type

A type literal in the syntax tree

TypeKind

GraphQL type kind

Value

Serializable value returned from query and field execution.

Traits

ExtractTypeFromStream

This trait is used in juniper::graphql_subscription macro to get stream’s item type that implements GraphQLValue from type alias provided by user.

FromInputValue

Parsing of an unstructured input value into a Rust data type.

GraphQLInterface

Maker trait for GraphQL interfaces.

GraphQLObject

Maker trait for GraphQL objects.

GraphQLSubscriptionType

Extension of GraphQLType trait with asynchronous subscription execution logic.

GraphQLSubscriptionValue

Extension of GraphQLValue trait with asynchronous subscription execution logic. It should be used with GraphQLValue in order to implement subscription resolvers on GraphQL objects.

GraphQLType

Primary trait used to expose Rust types in a GraphQL schema.

GraphQLTypeAsync

Extension of GraphQLType trait with asynchronous queries/mutations resolvers.

GraphQLUnion

Maker trait for GraphQL unions.

GraphQLValue

Primary trait used to resolve GraphQL values.

GraphQLValueAsync

Extension of GraphQLValue trait with asynchronous queries/mutations resolvers.

IntoFieldResult

Trait for wrapping Stream into Ok if it’s not Result.

ParseScalarValue

A trait used to convert a ScalarToken into a certain scalar value type

ScalarValue

A trait marking a type that could be used as internal representation of scalar values in juniper

SubscriptionConnection

Single subscription connection.

SubscriptionCoordinator

Global subscription coordinator trait.

ToInputValue

Losslessly clones a Rust data type into an InputValue.

Functions

execute

Execute a query in a provided schema

execute_sync

Execute a query synchronously in a provided schema

introspect

Execute the reference introspection query in the provided schema

resolve_into_stream

Resolve subscription into ValuesStream

Type Aliases

BoxFuture

An owned dynamically typed Future for use in cases where you can’t statically type your result or need to add some indirection.

LocalBoxFuture

BoxFuture, but without the Send requirement.

ParseScalarResult

The result of converting a string into a scalar value

Attribute Macros

graphql_interface

#[graphql_interface] macro for generating a GraphQL interface implementation for traits and its implementers.

graphql_object

#[graphql_object] macro for generating a GraphQL object implementation for structs with computable field resolvers (declared via a regular Rust impl block).

graphql_scalar

#[graphql_scalar] macro.is interchangeable with #[derive(GraphQLScalar)] macro, and is used for deriving a GraphQL scalar implementation.

graphql_subscription

#[graphql_subscription] macro for generating a GraphQL subscription implementation for structs with computable field resolvers (declared via a regular Rust impl block).

graphql_union

#[graphql_union] macro for deriving a GraphQL union implementation for traits.

Derive Macros
