hexeract-outbox-sql 0.4.0

//! SQL backends for the Hexeract outbox, built on `sqlx`.
//!
//! This crate implements the backend-agnostic [`hexeract_outbox`] contracts
//! ([`OutboxStore`], [`OutboxPublisher`]) on top of `sqlx`, with one
//! compile-time backend per Cargo feature:
//!
//! - `postgres` (default): [`PgOutboxStore`] / [`PgOutboxPublisher`]
//! - `mysql`: `MySqlOutboxStore` / `MySqlOutboxPublisher`
//! - `sqlite`: `SqliteOutboxStore` / `SqliteOutboxPublisher`
//!
//! The SQL dialect differences (placeholder style, row locking, timestamp
//! handling and schema DDL) are centralized in [`Dialect`], so the per-backend
//! stores share the statement templating and the envelope assembly logic.
//!
//! [`OutboxStore`]: hexeract_outbox::OutboxStore
//! [`OutboxPublisher`]: hexeract_outbox::OutboxPublisher
