Functions

call_setter 🔒 ^⚠

delete_property_by_id 🔒 ^⚠

Deletes the property id from object.

enumerate_global 🔒 ^⚠

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^⚠

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

latin1_bytes_from_id 🔒 ^⚠

Returns a slice of bytes corresponding to the bytes in the provided string id. Returns an error if the id is not a string, or the string contains non-latin1 characters.

may_resolve_global 🔒 ^⚠

Returns true if the resolve hook for this global may resolve the provided id. https://searchfox.org/mozilla-central/rev/f3c8c63a097b61bb1f01e13629b9514e09395947/dom/bindings/BindingUtils.cpp#2809 https://searchfox.org/mozilla-central/rev/f3c8c63a097b61bb1f01e13629b9514e09395947/js/public/Class.h#283-291

may_resolve_window 🔒 ^⚠

Returns true if the resolve hook for this window may resolve the provided id. https://searchfox.org/mozilla-central/rev/f3c8c63a097b61bb1f01e13629b9514e09395947/dom/base/nsGlobalWindowInner.cpp#3275 https://searchfox.org/mozilla-central/rev/f3c8c63a097b61bb1f01e13629b9514e09395947/js/public/Class.h#283-291

resolve_global 🔒 ^⚠

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

resolve_window 🔒 ^⚠

Resolve a lazy global property for a Window global.

set_dictionary_property^⚠

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

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.
