Type Alias mozjs::jsapi::ModuleResolveHook

pub type ModuleResolveHook = Option<unsafe extern "C" fn(_: *mut JSContext, _: Handle<Value>, _: Handle<*mut JSObject>) -> *mut JSObject>;

The HostResolveImportedModule hook.

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

This embedding-defined hook is used to implement module loading. It is called to get or create a module object corresponding to |moduleRequest| occurring in the context of the script or module with private value |referencingPrivate|.

The module specifier string for the request can be obtained by calling JS::GetModuleRequestSpecifier.

The private value for a script or module is set with JS::SetScriptPrivate or JS::SetModulePrivate. It’s assumed that the embedding can handle receiving either here.

This hook must obey the restrictions defined in the spec:

• Each time the hook is called with the same arguemnts, the same module must be returned.
• If a module cannot be created for the given arguments, an exception must be thrown.

This is a synchronous operation.
