Traits

CallPolicy 🔒

Functions

define_all_exposed_interfaces 🔒

Eagerly define all relevant WebIDL interface constructors on the provided global object.

define_dictionary_property 🔒

Define an own enumerable data property with name property on object. Returns Err(()) on JSAPI failure, or null object, and Ok(()) otherwise.

get_array_index_from_id 🔒

Get an array index from the given jsid. Returns None if the given jsid is not an integer.

get_dictionary_property 🔒 ^⚠

Get the property with name property from object. Returns Err(()) on JSAPI failure (there is a pending exception), and Ok(false) if there was no property with the given name.

has_own_property 🔒

Checks whether object has an own property named property. Returns Err(()) on JSAPI failure (there is a pending exception), and Ok(false) for null objects or when the property is not own.

has_property_on_prototype 🔒 ^⚠

Computes whether proxy has a property id on its prototype and stores the result in found.
