Module script::dom::bindings::utils

Various utilities to glue JavaScript and the DOM implementation together.

Structs

• DOMClass
  The struct that holds inheritance information for DOM object reflectors.
• DOMJSClass
  The JSClass used for DOM object reflectors.
• GlobalStaticData
  Static data associated with a global object.

Constants

• DOM_CALLBACKS
• DOM_PROTOTYPE_SLOT
  The index of the slot that contains a reference to the ProtoOrIfaceArray.
• DOM_PROTO_UNFORGEABLE_HOLDER_SLOT
  The index of the slot where the object holder of that interface’s unforgeable members are defined.
• JSCLASS_DOM_GLOBAL
  The flag set on the JSClasses for DOM global objects.

Traits

• AsCCharPtrPtr
• AsVoidPtr

Functions

• call_setter 🔒 ^⚠
• delete_property_by_id^⚠
  Deletes the property id from object.
• enumerate_global^⚠
  Enumerate lazy properties of a global object.
• exception_to_promise^⚠
  Coverts exception to promise rejection
• 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.
• generic_static_promise_method^⚠

• 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 Aliases

• ProtoOrIfaceArray
  An array of *mut JSObject of size PROTO_OR_IFACE_LENGTH.
