Crate graphql_toolkit_ast

A collection of Rust modules to process GraphQL documents

This module contains the AST types and traits for the GraphQL query language.

Modules

• indexmap
  IndexMap is a hash table where the iteration order of the key-value pairs is independent of the hash values of the keys.

Macros

• value
  Construct a ConstValue.

Structs

• ConstDirective
  A const GraphQL directive, such as @deprecated(reason: "Use the other field). This differs from Directive in that it uses ConstValue instead of Value.
• DeserializerError
  This type represents errors that can occur when deserializing.
• Directive
  A GraphQL directive, such as @deprecated(reason: "Use the other field").
• DirectiveDefinition
  The definition of a directive in a service.
• EnumType
  The definition of an enum.
• EnumValueDefinition
  The definition of a value inside an enum.
• ExecutableDocument
  An executable GraphQL file or request string.
• Field
  A field being selected on an object, such as name or weightKilos: weight(unit: KILOGRAMS).
• FieldDefinition
  The definition of a field inside an object or interface.
• FragmentDefinition
  The definition of a fragment, such as fragment userFields on User { name age }.
• FragmentSpread
  A fragment selector, such as ... userFields.
• InlineFragment
  An inline fragment selector, such as ... on User { name }.
• InputObjectType
  The definition of an input object.
• InputValueDefinition
  The definition of an input value inside the arguments of a field.
• InterfaceType
  The definition of an interface type.
• Name
  A GraphQL name.
• Number
  Represents a JSON number, whether integer or floating point.
• ObjectType
  The definition of an object type.
• OperationDefinition
  A GraphQL operation, such as mutation($content:String!) { makePost(content: $content) { id } }.
• OperationsIter
  An iterator over the operations of a document.
• Pos
  Original position of an element in source code.
• Positioned
  An AST node that stores its original position.
• SchemaDefinition
  The definition of the schema in a GraphQL service.
• SelectionSet
  A set of fields to be selected, for example { name age }.
• SerializerError
  This type represents errors that can occur when serializing.
• ServiceDocument
  A GraphQL file or request string defining a GraphQL service.
• Type
  A GraphQL type, for example String or [String!]!.
• TypeCondition
  A type a fragment can apply to (on followed by the type).
• TypeDefinition
  The definition of a type in a GraphQL service.
• UnionType
  The definition of a union type.
• VariableDefinition
  A variable definition inside a list of variable definitions, for example $name:String!.
• Variables
  Variables of a query.

Enums

• BaseType
  A GraphQL base type, for example String or [String!]. This does not include whether the type is nullable; for that see Type.
• ConstValue
  A resolved GraphQL value, for example 1 or "Hello World!".
• DirectiveLocation
  Where a directive can apply to.
• DocumentOperations
  The operations of a GraphQL document.
• OperationType
  The type of an operation; query, mutation or subscription.
• Selection
  A part of an object to be selected; a single field, a fragment spread or an inline fragment.
• TypeKind
  A kind of type; scalar, object, enum, etc.
• TypeSystemDefinition
  A definition concerning the type system of a GraphQL service.
• Value
  A GraphQL value, for example 1, $name or "Hello World!". This is ConstValue with variables.

Traits

• AstPositionExt
  Extension trait for adding position information to AST nodes.
• IntoAst
  A value-to-AST conversion trait that consumes the input value.

Functions

• from_value
  Interpret a ConstValue as an instance of type T.
• to_value
  Convert a T into ConstValue which is an enum that can represent any valid GraphQL data.
