1//! A Rust library for persisting Event Sourced entities to PostgreSQL
2//!
3//! This crate simplifies Event Sourcing persistence by automatically generating type-safe
4//! queries and operations for PostgreSQL. It decouples domain logic from persistence
5//! concerns while ensuring compile-time query verification via [sqlx](https://crates.io/crates/sqlx).
