// is only done once, in the browser process. These rules are validated after
// they have been converted into Mojo.
// In Core Runtime, we have a one-way flow from the untrusted embedder into the
// browser process, via a gRPC API. From there, the rules are converted into
// Mojo and then validated before being sent to renderer processes. No further
// conversion is performed, the Mojo types are used as is to apply the rewrites
// on URL requests.
// Converter returns |nullptr| if conversion is not possible.
