sqlmodel-postgres 0.2.2

//! PostgreSQL driver for SQLModel Rust.
//!
//! `sqlmodel-postgres` is the **Postgres driver** for the SQLModel ecosystem. It
//! implements the PostgreSQL wire protocol from scratch using asupersync's TCP
//! primitives and exposes a `Connection` implementation for query execution.
//!
//! # Role In The Architecture
//!
//! - Implements `sqlmodel-core::Connection` for Postgres
//! - Provides authentication, protocol framing, and type conversions
//! - Powers `sqlmodel-query` execution and `sqlmodel-session` persistence
//!
//! This crate implements the PostgreSQL wire protocol from scratch using
//! asupersync's TCP primitives. It provides:
//!
//! - Message framing and parsing
//! - Authentication (cleartext, MD5, SCRAM-SHA-256)
//! - Simple and extended query protocols
//! - Connection management with state machine
//! - Type conversion between Rust and PostgreSQL types
//!
//! # Type System
//!
//! The `types` module provides comprehensive type mapping between PostgreSQL
//! and Rust types, including:
//!
//! - OID constants for all built-in types
//! - Text and binary encoding/decoding
//! - Type registry for runtime type lookup
//!
//! # Example
//!
//! ```rust,ignore
//! use sqlmodel_postgres::{PgConfig, PgConnection};
//!
//! let config = PgConfig::new()
//!     .host("localhost")
//!     .port(5432)
//!     .user("postgres")
//!     .database("mydb");
//!
//! let conn = PgConnection::connect(config)?;
//! ```
