Struct AttributeType

pub struct AttributeType {
    pub label: String,
    pub value_type: Option<ValueType>,
}

Attribute types represent properties that other types can own.

Attribute types have a value type. This value type is fixed and unique for every given instance of the attribute type.

Other types can own an attribute type. That means that instances of these other types can own an instance of this attribute type. This usually means that an object in our domain has a property with the matching value.

Multiple types can own the same attribute type, and different instances of the same type or different types can share ownership of the same attribute instance.

Fields

label: String

value_type: Option<ValueType>

Implementations

impl AttributeType

pub fn label(&self) -> &str

Retrieves the unique label of the AttributeType.

Examples

attribute_type.label()

pub fn value_type(&self) -> Option<&ValueType>

Retrieves the ValueType of the AttributeType.

Examples

attribute_type.value_type()

Trait Implementations

impl Clone for AttributeType

fn clone(&self) -> AttributeType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeType

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

Formats the value using the given formatter.

impl Display for AttributeType

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

Formats the value using the given formatter.

impl PartialEq for AttributeType

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