cratestack_sql/
lib.rs

1//! Dialect-agnostic SQL primitives shared by the Postgres (`cratestack-sqlx`)
2//! and SQLite (`cratestack-rusqlite`) backends.
3//!
4//! This crate carries the type definitions every backend agrees on:
5//!
6//! - [`SqlValue`] / [`SqlColumnValue`] — value envelopes used to bind data
7//! - [`CreateModelInput`] / [`UpdateModelInput`] / [`UpsertModelInput`] —
8//!   traits the codegen emits
9//! - [`Filter`] / [`FilterExpr`] / [`FieldRef`] — query AST
10//! - [`OrderClause`] / [`SortDirection`] — ordering AST
11//! - [`ModelDescriptor`] / [`ModelColumn`] / [`CreateDefault`] — schema
12//!   metadata baked into compiled code by `include_schema!`
13//!
14//! Rendering SQL strings, executing queries, and any DB-driver coupling
15//! live in the backend crates.
