Struct DataSourceIntrospectionModelFieldType

#[non_exhaustive]
pub struct DataSourceIntrospectionModelFieldType {
    pub kind: Option<String>,
    pub name: Option<String>,
    pub type: Option<Box<DataSourceIntrospectionModelFieldType>>,
    pub values: Option<Vec<String>>,
}

Represents the type data for each field retrieved from the introspection.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: Option<String>

Specifies the classification of data. For example, this could be set to values like Scalar or NonNull to indicate a fundamental property of the field.

Valid values include:

• Scalar: Indicates the value is a primitive type (scalar).

• NonNull: Indicates the field cannot be null.

• List: Indicates the field contains a list.

name: Option<String>

The name of the data type that represents the field. For example, String is a valid name value.

type: Option<Box<DataSourceIntrospectionModelFieldType>>

The DataSourceIntrospectionModelFieldType object data. The type is only present if DataSourceIntrospectionModelFieldType.kind is set to NonNull or List.

The type typically contains its own kind and name fields to represent the actual type data. For instance, type could contain a kind value of Scalar with a name value of String. The values Scalar and String will be collectively stored in the values field.

values: Option<Vec<String>>

The values of the type field. This field represents the AppSync data type equivalent of the introspected field.

Implementations

impl DataSourceIntrospectionModelFieldType

pub fn kind(&self) -> Option<&str>

Specifies the classification of data. For example, this could be set to values like Scalar or NonNull to indicate a fundamental property of the field.

Valid values include:

• Scalar: Indicates the value is a primitive type (scalar).

• NonNull: Indicates the field cannot be null.

• List: Indicates the field contains a list.

pub fn name(&self) -> Option<&str>

The name of the data type that represents the field. For example, String is a valid name value.

pub fn type(&self) -> Option<&DataSourceIntrospectionModelFieldType>

The DataSourceIntrospectionModelFieldType object data. The type is only present if DataSourceIntrospectionModelFieldType.kind is set to NonNull or List.

The type typically contains its own kind and name fields to represent the actual type data. For instance, type could contain a kind value of Scalar with a name value of String. The values Scalar and String will be collectively stored in the values field.

pub fn values(&self) -> &[String]

The values of the type field. This field represents the AppSync data type equivalent of the introspected field.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .values.is_none().

impl DataSourceIntrospectionModelFieldType

pub fn builder() -> DataSourceIntrospectionModelFieldTypeBuilder

Creates a new builder-style object to manufacture DataSourceIntrospectionModelFieldType.

Trait Implementations

impl Clone for DataSourceIntrospectionModelFieldType

fn clone(&self) -> DataSourceIntrospectionModelFieldType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataSourceIntrospectionModelFieldType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DataSourceIntrospectionModelFieldType

fn eq(&self, other: &DataSourceIntrospectionModelFieldType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
