// This class is needed to copy a FetchClientSettingsObjectSnapshot across

// threads (SecurityOrigin for example).
// There are some rules / restrictions:
//   - This struct cannot contain an object that cannot be transferred across
//     threads.
//   - Non-thread-safe members need explicit copying rather than the copy
//     constructor or the assignment operator.
//   - This struct cannot contain any garbage-collected object because this
//     data can be constructed on a thread which runs without Oilpan.

// This takes a partial snapshot of the execution context's states so that an
// instance of this class can be passed to another thread without cross-thread
// synchronization. Don't keep this object persistently, instead create a new
// instance per each "fetch a module script graph" algorithm:
// https://html.spec.whatwg.org/C/#fetch-a-module-script-tree
// https://html.spec.whatwg.org/C/#fetch-a-module-worker-script-tree
//
// This class should be used only for main worker (worklet) script loading. For
// other resources, FetchClientSettingsObjectImpl should be used. See the class
// level comments on that class.
