Struct Attribute 

pub struct Attribute {
    pub iid: IID,
    pub value: Value,
    pub type_: Option<AttributeType>,
}

Attribute is an instance of the attribute type and has a value. This value is fixed and unique for every given instance of the attribute type. Attributes can be uniquely addressed by their type and value.

Fields

iid: IID

The unique id of this Attribute (internal use only)

value: Value

The (dataful) value of this attribute

type_: Option<AttributeType>

The type which this Attribute belongs to

Implementations

impl Attribute

pub fn type_(&self) -> Option<&AttributeType>

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 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.
