//! Crate-internal types for interacting with Remote Settings (`rs`). Types in
//! this module describe records and attachments in the Suggest Remote Settings
//! collection.
//!
//! To add a new suggestion `T` to this component, you'll generally need to:
//!
//! 1. Add a variant named `T` to [`SuggestRecord`]. The variant must have a
//! `#[serde(rename)]` attribute that matches the suggestion record's
//! `type` field.
//! 2. Define a `DownloadedTSuggestion` type with the new suggestion's fields,
//! matching their attachment's schema. Your new type must derive or
//! implement [`serde::Deserialize`].
//! 3. Update the database schema in the [`schema`] module to store the new
//! suggestion.
//! 4. Add an `insert_t_suggestions()` method to [`db::SuggestDao`] that
//! inserts `DownloadedTSuggestion`s into the database.
//! 5. Update [`store::SuggestStoreInner::ingest()`] to download, deserialize,
//! and store the new suggestion.
//! 6. Add a variant named `T` to [`suggestion::Suggestion`], with the fields
//! that you'd like to expose to the application. These can be the same
//! fields as `DownloadedTSuggestion`, or slightly different, depending on
//! what the application needs to show the suggestion.
//! 7. Update the `Suggestion` enum definition in `suggest.udl` to match your
//! new [`suggestion::Suggestion`] variant.
//! 8. Update any [`db::SuggestDao`] methods that query the database to include
//! the new suggestion in their results, and return `Suggestion::T` variants
//! as needed.
