1//! Row decoding trait for SQLite.
2//!
3//! Mirrors `sqlx::FromRow<PgRow>` for the rusqlite side. The model macro
4//! emits an impl of this trait when targeting the SQLite backend, so user
5//! code never sees this directly — it just calls `find_many().run()` and
6//! receives `Vec<UserModel>`.

10/// Decode a model from a rusqlite row.
11///
12/// Implementations are free to use either positional (`row.get(0)`) or named
13/// (`row.get("col")`) lookups. The codegen uses named lookups against the
14/// model's `rust_name` aliases, matching the projection produced by
15/// [`cratestack_sql::ModelDescriptor::select_projection`].

20/// Partial-row decoder — mirrors [`cratestack_sqlx::FromPartialPgRow`]
21/// for the embedded backend. The macro emits this impl alongside
22/// `FromRusqliteRow`; users see it only as the bound on the typed
23/// builder's `T` generic when they call `.select(...)`.
