Functions

call_setter 🔒 ^⚠

create_typed_array

Creates a Float32 array

delete_property_by_id^⚠

Deletes the property id from object.

enumerate_global^⚠

Enumerate lazy properties of a global object.

finalize_global^⚠

Drop the resources held by reserved slots of a global object

find_enum_value^⚠

Find the enum equivelent of a string given by v in pairs. Returns Err(()) on JSAPI failure (there is a pending exception), and Ok((None, value)) if there was no matching string.

generic_call 🔒 ^⚠

generic_getter^⚠

Generic getter of IDL interface.

generic_lenient_getter^⚠

Generic lenient getter of IDL interface.

generic_lenient_setter^⚠

Generic lenient setter of IDL interface.

generic_method^⚠

Generic method of IDL interface.

generic_setter^⚠

Generic setter of IDL interface.

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.

get_property_on_prototype^⚠

Gets the property id on proxy’s prototype. If it exists, *found is set to true and *vp to the value, otherwise *found is set to false.

get_proto_or_iface_array

Returns the ProtoOrIfaceArray for the given global object. Fails if global is not a DOM global object.

has_property_on_prototype^⚠

Returns whether proxy has a property id on its prototype.

instance_class_has_proto_at_depth 🔒 ^⚠

is_platform_object 🔒

is_platform_object_dynamic

Returns wether obj is a platform object using dynamic unwrap https://heycam.github.io/webidl/#dfn-platform-object

is_platform_object_static

Returns wether obj is a platform object using static unwrap https://heycam.github.io/webidl/#dfn-platform-object

resolve_global^⚠

Resolve a lazy global property, for interface objects and named constructors.

set_dictionary_property

Set the property with name property from object. Returns Err(()) on JSAPI failure, or null object, and Ok(()) otherwise

to_frozen_array

Returns a JSVal representing a frozen array of ports

trace_global^⚠

Trace the resources held by reserved slots of a global object

Type Definitions

ProtoOrIfaceArray

An array of *mut JSObject of size PROTO_OR_IFACE_LENGTH.
