Module boa_engine::property

Boa’s implementation of ECMAScript’s Property Descriptor.

The Property Descriptor type is used to explain the manipulation and reification of Object property attributes. Values of the Property Descriptor type are Records. Each field’s name is an attribute name and its value is a corresponding attribute value as specified in 6.1.7.1. In addition, any field may be present or absent. The schema name used within this specification to tag literal descriptions of Property Descriptor records is PropertyDescriptor.

Structs

  This represents an ECMAScript Property AKA The Property Descriptor.
• PropertyDescriptorBuilder

Enums

• PropertyKey
