[−][src]Enum juniper::TypeKind
GraphQL type kind
The GraphQL specification defines a number of type kinds - the meta type
of a type.
Variants
Scalar types
Scalar types appear as the leaf nodes of GraphQL queries. Strings,
numbers, and booleans are the built in types, and while it's possible
to define your own, it's relatively uncommon.
Object types
The most common type to be implemented by users. Objects have fields
and can implement interfaces.
Interface types
Interface types are used to represent overlapping fields between
multiple types, and can be queried for their concrete type.
Union types
Unions are similar to interfaces but can not contain any fields on
their own.
Enum types
Like scalars, enum types appear as the leaf nodes of GraphQL queries.
Input objects
Represents complex values provided in queries into the system.
List types
Represent lists of other types. This library provides implementations
for vectors and slices, but other Rust types can be extended to serve
as GraphQL lists.
Non-null types
In GraphQL, nullable types are the default. By putting a !
after a
type, it becomes non-nullable.
