1453338 - Make it possible to implement IPDL protocols in Rust

Status: RESOLVED DUPLICATE of bug 1379739

(Core :: IPC, enhancement, P3)

Description

[Alex Gaynor [:Alex_Gaynor]]

As we strengthen the process sandbox, the security of our IPC mechanisms because more and more paramount. Like the rendering engine itself, existing C++ IPC struggles with all the memory unsafety that using C++ entails.

I imagine this would look like adding Rust codegen to the IPDL codegen, as well as adding a small C++ shim to plug the Rust APIs into the existing IProtocol class hierarchy. We'd want to make sure this worked well for both top-level protocols and for sub-protocols.
