Struct ValueObject 

pub struct ValueObject {
    pub entries: Vec<(String, Value)>,
}

An ordered sequence of named Values representing a document.

ValueObject is the named counterpart to ValueRecord: where a record is positional, an object carries a key for each field. It is the wire form of a #[document] value — typed by the structural Type::Object — and the only form in which a document crosses the driver boundary, in either direction. The query engine builds a ValueObject from a positional record (using the field names from the embedded model schema) just before handing a document-stored value to a driver, and raises a driver-decoded object back to the positional record on the way in. Drivers convert a ValueObject structurally — to a JSON object, a BSON sub-document, a DynamoDB map — without needing the schema; the embedded model’s identity never reaches them.

Entries are kept in insertion order. Keys are not deduplicated; writers always build objects from a schema, so keys are unique by construction.

Fields

entries: Vec<(String, Value)>

The named field values, in insertion order.

Implementations

impl ValueObject

pub fn from_vec(entries: Vec<(String, Value)>) -> Self

Creates a ValueObject from a vector of (key, value) pairs.

pub fn iter(&self) -> Iter<'_, (String, Value)>

Iterates over the (key, value) entries in insertion order.

Trait Implementations

impl Clone for ValueObject

fn clone(&self) -> ValueObject

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueObject

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

Formats the value using the given formatter.

impl Default for ValueObject

fn default() -> ValueObject

Returns the “default value” for a type.

impl From<ValueObject> for Value

fn from(value: ValueObject) -> Self

Converts to this type from the input type.

impl PartialEq for ValueObject

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