Could you remove this and write StructTraits in
service_worker_types_traits.cc/h?

[leonhsl(Using Gerrit), 2016/12/02 08:36:44]

Yeah this work should be done sooner or later, but I see
|ServiceWorkerFetchRequest| is already  reusing the old IPC traits so I'd like
to focus on migrating IPC messages firstly, then create typemappings for them
all later. I suppose such way could avoid some additional work when we finally
decided where will these codes be decoupled out from //content :) Also, the
typemapping codes would be big and make the CL less-readable.

Sounds good! Let's move them on another CL after mojofication of event
dispatcher.
