• PrototypeCheck 🔒
• StringificationBehavior 🔒
  Behavior for stringification of JSVals.

Constants

• DOM_OBJECT_SLOT 🔒
  The index of the slot wherein a pointer to the reflected DOM object is stored for non-proxy bindings.

Traits

• DerivedFrom 🔒
  A trait to mark an IDL interface as deriving from another one.
• FromJSValConvertible 🔒
  A trait to convert JSVals to Rust types.
• IDLInterface 🔒
  A trait to check whether a given JSObject implements an IDL interface.
• ToJSValConvertible 🔒
  A trait to convert Rust types to JSVals.

Functions

• get_dom_class 🔒 ^⚠
  Get the DOMClass from obj, or Err(()) if obj is not a DOM object.
• get_property 🔒 ^⚠
  Get a property from a JS object, and convert it to a Rust value.
• get_property_jsval 🔒 ^⚠
  Get a property from a JS object.
• is_array_like 🔒 ^⚠
  Returns whether value is an array-like object (Array, FileList, HTMLCollection, HTMLFormControlsCollection, HTMLOptionsCollection, NodeList).
• is_dom_proxy 🔒 ^⚠
  Returns whether obj is a DOM object implemented as a proxy.
• jsid_to_string 🔒 ^⚠
  Convert id to a DOMString. Returns None if id is not a string or integer.
• jsstring_to_str 🔒 ^⚠
  Convert the given JSString to a DOMString. Fails if the string does not contain valid UTF-16.
• native_from_handlevalue 🔒 ^⚠
  Get a *const T for a DOM object accessible from a HandleValue. Caller is responsible for throwing a JS exception if needed in case of error.
• native_from_object 🔒 ^⚠
  Get a *const T for a DOM object accessible from a JSObject.
• native_from_object_static 🔒 ^⚠
  Get a *const T for a DOM object accessible from a JSObject, where the DOM object is guaranteed not to be a wrapper.
• private_from_object 🔒 ^⚠
  Get the private pointer of a DOM object from a given reflector.
• private_from_proto_check 🔒 ^⚠
  Get a *const libc::c_void for the given DOM object, unwrapping any wrapper around it first, and checking if the object is of the correct type.
• root_from_handleobject 🔒
  Get a DomRoot<T> for a DOM object accessible from a HandleObject.
• root_from_handlevalue 🔒 ^⚠
  Get a DomRoot<T> for a DOM object accessible from a HandleValue. Caller is responsible for throwing a JS exception if needed in case of error.
• root_from_object 🔒 ^⚠
  Get a DomRoot<T> for the given DOM object, unwrapping any wrapper around it first, and checking if the object is of the correct type.
• root_from_object_static 🔒
  Get a DomRoot<T> for the given DOM object, unwrapping any wrapper around it first, and checking if the object is of the correct type.
