Property declaration for a closed graph type.

Fields

name: DbString

Property name.

value_type: PropertyValueType

Declared value type.

list_element_type: Option<PropertyElementType>

Declared element type when PropertyTypeDef::value_type is List.

required: bool

true means NOT NULL / required.

default: Option<PropertyDefaultValue>

Default value materialized when the property is omitted on create.

immutable: bool

Whether updates to this property are forbidden after creation.

unique: bool

Whether non-null property values must be unique within the declaring type.

decimal_type: Option<DecimalType>

Declared decimal precision/scale when PropertyTypeDef::value_type is Decimal.

character_string_type: Option<CharacterStringType>

Declared character-string length when PropertyTypeDef::value_type is String.

byte_string_type: Option<ByteStringType>

Declared byte-string length when PropertyTypeDef::value_type is Bytes.

record_field_types: Option<RecordFieldTypes>

Declared field types when PropertyTypeDef::value_type is RecordTyped. Some only for closed/typed RECORD declarations; None for open Record and every non-record value type (symmetric to PropertyTypeDef::list_element_type).

Trait Implementations

impl Archive for PropertyTypeDef

where DbString: Archive, PropertyValueType: Archive, Option<PropertyElementType>: Archive, bool: Archive, Option<PropertyDefaultValue>: Archive, Option<DecimalType>: Archive, Option<CharacterStringType>: Archive, Option<ByteStringType>: Archive, Option<RecordFieldTypes>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedPropertyTypeDef

The archived representation of this type.

type Resolver = PropertyTypeDefResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for PropertyTypeDef

fn clone(&self) -> PropertyTypeDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyTypeDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PropertyTypeDef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<PropertyTypeDef, __D> for Archived<PropertyTypeDef>

where DbString: Archive, <DbString as Archive>::Archived: Deserialize<DbString, __D>, PropertyValueType: Archive, <PropertyValueType as Archive>::Archived: Deserialize<PropertyValueType, __D>, Option<PropertyElementType>: Archive, <Option<PropertyElementType> as Archive>::Archived: Deserialize<Option<PropertyElementType>, __D>, bool: Archive, <bool as Archive>::Archived: Deserialize<bool, __D>, Option<PropertyDefaultValue>: Archive, <Option<PropertyDefaultValue> as Archive>::Archived: Deserialize<Option<PropertyDefaultValue>, __D>, Option<DecimalType>: Archive, <Option<DecimalType> as Archive>::Archived: Deserialize<Option<DecimalType>, __D>, Option<CharacterStringType>: Archive, <Option<CharacterStringType> as Archive>::Archived: Deserialize<Option<CharacterStringType>, __D>, Option<ByteStringType>: Archive, <Option<ByteStringType> as Archive>::Archived: Deserialize<Option<ByteStringType>, __D>, Option<RecordFieldTypes>: Archive, <Option<RecordFieldTypes> as Archive>::Archived: Deserialize<Option<RecordFieldTypes>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<PropertyTypeDef, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for PropertyTypeDef

fn eq(&self, other: &PropertyTypeDef) -> 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.

impl Serialize for PropertyTypeDef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<__S: Fallible + ?Sized> Serialize<__S> for PropertyTypeDef

where DbString: Serialize<__S>, PropertyValueType: Serialize<__S>, Option<PropertyElementType>: Serialize<__S>, bool: Serialize<__S>, Option<PropertyDefaultValue>: Serialize<__S>, Option<DecimalType>: Serialize<__S>, Option<CharacterStringType>: Serialize<__S>, Option<ByteStringType>: Serialize<__S>, Option<RecordFieldTypes>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
