Type Alias mozjs_sys::jsapi::JS::ModuleMetadataHook

pub type ModuleMetadataHook = Option<unsafe extern "C" fn(cx: *mut JSContext, privateValue: Handle<Value>, metaObject: Handle<*mut JSObject>) -> bool>;

The module metadata hook.

See: https://tc39.es/ecma262/#sec-hostgetimportmetaproperties

Populate the |metaObject| object returned when import.meta is evaluated in the context of the script or module with private value |privateValue|.

This is based on the spec’s HostGetImportMetaProperties hook but defines properties on the meta object directly rather than returning a list.
