Represents a GraphQL input type.

Required Associated Types

type RawValueType

The raw type used for validator.

Usually it is Self, but the wrapper type is its internal type.

For example:

i32::RawValueType is i32 Option<i32>::RawValueType is i32.

Required Methods

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

fn parse(value: Option<Value>) -> InputValueResult<Self>

Parse from Value. None represents undefined.

fn to_value(&self) -> Value

Convert to a Value for introspection.

fn as_raw_value(&self) -> Option<&Self::RawValueType>

Returns a reference to the raw value.

Provided Methods

fn qualified_type_name() -> String

Qualified typename.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
