Struct Attribute 

pub struct Attribute {
    pub id: AttributeId,
    pub name: String,
    pub data_type: DataType,
    pub is_primary: bool,
    pub is_partial_key: bool,
    pub is_optional: bool,
    pub kind: AttributeKind,
    pub children: Vec<AttributeId>,
}

An attribute belonging to either an Entity or a Relationship.

Fields

id: AttributeId

Unique handle within the owning model.

name: String

Display name (e.g. "first_name").

data_type: DataType

Logical data type (mapped to a column type during conversion).

is_primary: bool

Whether this attribute participates in the entity’s primary identifier.

is_partial_key: bool

Whether this attribute is a partial key — combined with the owning entity’s identifying relationship to form a key (typical for weak entities).

is_optional: bool

Whether the attribute admits a null value.

kind: AttributeKind

Structural kind of the attribute.

children: Vec<AttributeId>

For composite attributes, the IDs of the sub-attributes that compose this one. Empty for non-composite attributes.

Trait Implementations

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attribute

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Attribute

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Attribute

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
