1//! # parsql-postgres
2//!
3//! Synchronous PostgreSQL integration for parsql.
4//! This crate provides synchronous APIs for working with PostgreSQL databases.
5//!
6//! ## Features
7//!
8//! - Synchronous PostgreSQL operations
9//! - Automatic SQL query generation
10//! - Secure parameter management
11//! - Generic CRUD operations
12//! - Transaction support
13//! - Extension methods for the Client object
14//!
15//! ## Usage
16//!
17//! ```rust,no_run
18//! use postgres::{Client, NoTls, Error};
19//! use parsql::postgres::{fetch, insert};
20//!
21//! #[derive(Insertable, SqlParams)]
22//! #[table("users")]
23//! pub struct InsertUser {
24//!     pub name: String,
25//!     pub email: String,
26//! }
27//!
28//! #[derive(Queryable, SqlParams, FromRow)]
29//! #[table("users")]
30//! #[where_clause("id = $")]
31//! pub struct GetUser {
32//!     pub id: i32,
33//!     pub name: String,
34//!     pub email: String,
35//! }
36//!
37//! fn main() -> Result<(), Error> {
38//!     let mut client = Client::connect(
39//!         "host=localhost user=postgres dbname=test",
40//!         NoTls,
41//!     )?;
42//!
43//!     // Insert a new user
44//!     let insert_user = InsertUser {
45//!         name: "John".to_string(),
46//!         email: "[email protected]".to_string(),
47//!     };
48//!
49//!     let id = insert(&mut client, insert_user)?;
50//!
51//!     // Get the user back
52//!     let get_user = GetUser::new(id as i32);
53//!     let user = fetch(&mut client, &get_user)?;
54//!
55//!     println!("User: {:?}", user);
56//!     Ok(())
57//! }
58//! ```
59//!
60//! ## Using Extension Methods
61//!
62//! You can also use the extension methods directly on the Client object:
63//!
64//! ```rust,no_run
65//! use postgres::{Client, NoTls, Error};
66//! use parsql::postgres::CrudOps;  // Import the trait
67//! use parsql::macros::{Insertable, SqlParams, Queryable, FromRow};
68//!
69//! #[derive(Insertable, SqlParams)]
70//! #[table("users")]
71//! pub struct InsertUser {
72//!     pub name: String,
73//!     pub email: String,
74//! }
75//!
76//! #[derive(Queryable, FromRow, SqlParams)]
77//! #[table("users")]
78//! #[where_clause("id = $1")]
79//! pub struct GetUser {
80//!     pub id: i32,
81//!     pub name: String,
82//!     pub email: String,
83//! }
84//!
85//! fn main() -> Result<(), Error> {
86//!     let mut client = Client::connect("host=localhost user=postgres", NoTls)?;
87//!
88//!     // Insert a new user using extension method
89//!     let insert_user = InsertUser {
90//!         name: "John".to_string(),
91//!         email: "[email protected]".to_string(),
92//!     };
93//!
94//!     let rows_affected = client.insert(insert_user)?;
95//!
96//!     // Get the user back using extension method
97//!     let get_user = GetUser {
98//!         id: 1,
99//!         name: String::new(),
100//!         email: String::new(),
101//!     };
102//!
103//!     let user = client.fetch(&get_user)?;
104//!
105//!     println!("User: {:?}", user);
106//!     Ok(())
107//! }
108//! ```
109//!
110//! ## Using Transactions
111//!
112//! You can also use transactions to ensure atomicity of operations:
113//!
114//! ```rust,no_run
115//! use postgres::{Client, NoTls, Error};
116//! use parsql::postgres::transactional::{begin, tx_insert, tx_update};
117//!
118//! #[derive(Insertable, SqlParams)]
119//! #[table("users")]
120//! pub struct InsertUser {
121//!     pub name: String,
122//!     pub email: String,
123//! }
124//!
125//! #[derive(Updateable, UpdateParams)]
126//! #[table("users")]
127//! #[where_clause("id = $1")]
128//! pub struct UpdateUser {
129//!     pub id: i32,
130//!     pub email: String,
131//! }
132//!
133//! fn main() -> Result<(), Error> {
134//!     let mut client = Client::connect(
135//!         "host=localhost user=postgres dbname=test",
136//!         NoTls,
137//!     )?;
138//!
139//!     // Start a transaction
140//!     let tx = begin(&mut client)?;
141//!
142//!     // Insert a new user within the transaction
143//!     let insert_user = InsertUser {
144//!         name: "John".to_string(),
145//!         email: "[email protected]".to_string(),
146//!     };
147//!
148//!     let (tx, _) = tx_insert(tx, insert_user)?;
149//!
150//!     // Update the user within the same transaction
151//!     let update_user = UpdateUser {
152//!         id: 1,
153//!         email: "[email protected]".to_string(),
154//!     };
155//!
156//!     let (tx, _) = tx_update(tx, update_user)?;
157//!
158//!     // Commit the transaction
159//!     tx.commit()?;
160//!     Ok(())
161//! }
162//! ```
