// Handles speculation-rules bases prefetches.
// TODO(isaboori  crbug.com/1384496): Currently Prefetcher class supports the
// integration of speculation rule based prefetches with the DevTools. It serves
// as an abstraction layer to avoid implementing the DevTools logic twice in
// SpeculationHostDelegate and PrefetchDocumentManager. After the refactoring of
// SpeculationHostDelegate, we can get rid of this layer and implement all the
// logic in a single class by merging existing Prefetcher and
// PrefetchDocumentManager into a single class. We should also rename
// SpeculationHostDevToolsObserver to PrefetcherDevToolsObserver and the class
// declaration should be moved to this header file.
