BaseFeature.sys.mjs Base class for quick suggest features. It can be extended to implement a feature that is part of the larger quick suggest feature and that should be enabled only when quick suggest is enabled. You can extend this class as an alternative to implementing your feature directly in `QuickSuggest`. Doing so has the following advantages: - If your feature is gated on a Nimbus variable or preference, `QuickSuggest` will manage its lifetime automatically. This is really only useful if the feature has state that must be initialized when the feature is enabled and uninitialized when it's disabled. - Encapsulation. You can keep all the code related to your feature in one place, without mixing it with unrelated code and cluttering up `QuickSuggest`. You can also test it in isolation from `QuickSuggest`. - Remote settings management. You can register your feature with `QuickSuggestRemoteSettings` and it will be called at appropriate times to sync from remote settings. - If your feature also serves suggestions from remote settings, you can implement one method, `queryRemoteSettings()`, to hook into `UrlbarProviderQuickSuggest`. - Your feature will automatically get its own logger. To register your subclass with `QuickSuggest`, add it to the `FEATURES` const in QuickSuggest.sys.mjs. 11676

SuggestBackendMl.sys.mjs The Suggest ML backend. Both the ML and Rust backends can be enabled at the same time. Features can support both backends and decide which one to use per query. 2735
SuggestBackendRust.sys.mjs The Suggest Rust backend. Not used when the remote settings JS backend is enabled. This class returns suggestions served by the Rust component. These are the primary related architectural pieces (see bug 1851256 for details): (1) The `suggest` Rust component, which lives in the application-services repo [1] and is periodically vendored into mozilla-central [2] and then built into the Firefox binary. (2) `suggest.udl`, which is part of the Rust component's source files and defines the interface exposed to foreign-function callers like JS [3, 4]. (3) `RustSuggest.sys.mjs` [5], which contains the JS bindings generated from `suggest.udl` by UniFFI. The classes defined in `RustSuggest.sys.mjs` are what we consume here in this file. If you have a question about the JS interface to the Rust component, try checking `RustSuggest.sys.mjs`, but as you get accustomed to UniFFI JS conventions you may find it simpler to refer directly to `suggest.udl`. (4) `config.toml` [6], which defines which functions in the JS bindings are sync and which are async. Functions default to the "worker" thread, which means they are async. Some functions are "main", which means they are sync. Async functions return promises. This information is reflected in `RustSuggest.sys.mjs` of course: If a function is "worker", its JS binding will return a promise, and if it's "main" it won't.
