1815014 - Create RemoteSettings Rust client

Status: RESOLVED FIXED

(Fenix :: Experimentation and Telemetry, task)

Description

[Matt Tighe [:matt-tighe]]

This is a meta issue to track the implementation of a Remote Settings (RS) client written in Rust. The ADR defining this work can be found here.

In short, this will comprise the following tasks:

• [x] Create a new top-level RS client component for high-level languages. Add UniFFI bindings and stub the API with todo!() macros.
• [x] Identify and move the relevant Nimbus code into a new shared support component.
• [x] Move relevant tests from Nimbus to shared support component.
• [x] Update Nimbus to use new shared component. PR
• [approved] Update top-level RS client to use new shared component instead of stubs.
• [in progress] Identify any impact on the Nimbus android/swift code - in particular, any shared configuration and initialization code identified above in the application-services repo.

For now, marking this as a part of 1818318, but in reality, these two metas can probably just be merged into one.

Closed small Nimbus follow-up with this patch

The patch that implements this client has been approved, but is going through a last minute cycle with moving some types around to best prepare for an iOS release, which has some specific gotchas due to how app-services is built for that platform. I've run into a bit of trouble working through that, and so am waiting for some assistance from some folks with deeper Rust experience.
