Enum PropertyElementType 

#[non_exhaustive]
pub enum PropertyElementType {
    Scalar(PropertyValueType),
    CharacterString(CharacterStringType),
    Decimal(DecimalType),
    ByteString(ByteStringType),
    List(Box<PropertyElementType>),
    NotNull(Box<PropertyElementType>),
}

Persistable element-type descriptor for LIST<T> property declarations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Scalar(PropertyValueType)

Scalar list element type.

CharacterString(CharacterStringType)

STRING list element type with a user-specified length envelope.

Decimal(DecimalType)

DECIMAL list element type with a user-specified precision/scale envelope.

ByteString(ByteStringType)

BYTES list element type with a user-specified length envelope.

List(Box<PropertyElementType>)

Nested list element type.

NotNull(Box<PropertyElementType>)

Explicitly non-null element type.

Implementations

impl PropertyElementType

pub const fn value_type(&self) -> PropertyValueType

Return the coarse property-value type for this descriptor.

pub fn matches(&self, value: &Value) -> bool

Return true when value belongs to this element type.

Trait Implementations

impl Archive for PropertyElementType

where PropertyValueType: Archive, CharacterStringType: Archive, DecimalType: Archive, ByteStringType: Archive,

type Archived = ArchivedPropertyElementType

The archived representation of this type.

type Resolver = PropertyElementTypeResolver

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 as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

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

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.

impl Clone for PropertyElementType

fn clone(&self) -> PropertyElementType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyElementType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PropertyElementType

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<PropertyElementType, __D> for Archived<PropertyElementType>

where __D::Error: Source, PropertyValueType: Archive, <PropertyValueType as Archive>::Archived: Deserialize<PropertyValueType, __D>, CharacterStringType: Archive, <CharacterStringType as Archive>::Archived: Deserialize<CharacterStringType, __D>, DecimalType: Archive, <DecimalType as Archive>::Archived: Deserialize<DecimalType, __D>, ByteStringType: Archive, <ByteStringType as Archive>::Archived: Deserialize<ByteStringType, __D>,

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

Deserializes using the given deserializer

impl Eq for PropertyElementType

impl Hash for PropertyElementType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PropertyElementType

fn eq(&self, other: &PropertyElementType) -> 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 PropertyElementType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<__S> Serialize<__S> for PropertyElementType

where __S: Writer + Fallible + ?Sized, PropertyValueType: Serialize<__S>, CharacterStringType: Serialize<__S>, DecimalType: Serialize<__S>, ByteStringType: 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.
