Traits

DerivedFrom

A trait to mark an IDL interface as deriving from another one.

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.

private_from_proto_check_static 🔒 ^⚠

Get a *const libc::c_void for the given DOM object, unless it is a DOM wrapper, 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.

windowproxy_from_handlevalue^⚠

Get a DomRoot<T> for a WindowProxy accessible from a HandleValue. Caller is responsible for throwing a JS exception if needed in case of error.
