# SAL PostgreSQL Client
|
||||
|
||||
The SAL PostgreSQL Client (`sal-postgresclient`) is an independent package that provides a simple and efficient way to interact with PostgreSQL databases in Rust. It offers connection management, query execution, a builder pattern for flexible configuration, and PostgreSQL installer functionality using nerdctl.
|
||||
|
||||
## Features
|
||||
|
||||
- **Connection Management**: Automatic connection handling and reconnection
|
||||
- **Query Execution**: Simple API for executing queries and fetching results
|
||||
- **Builder Pattern**: Flexible configuration with authentication support
|
||||
- **Environment Variable Support**: Easy configuration through environment variables
|
||||
- **Thread Safety**: Safe to use in multi-threaded applications
|
||||
- **PostgreSQL Installer**: Install and configure PostgreSQL using nerdctl containers
|
||||
- **Rhai Integration**: Scripting support for PostgreSQL operations
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic Usage
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::{execute, query, query_one};
|
||||
|
||||
// Execute a query
|
||||
let create_table_query = "CREATE TABLE IF NOT EXISTS users (id SERIAL PRIMARY KEY, name TEXT)";
|
||||
execute(create_table_query, &[]).expect("Failed to create table");
|
||||
|
||||
// Insert data
|
||||
let insert_query = "INSERT INTO users (name) VALUES ($1) RETURNING id";
|
||||
let rows = query(insert_query, &[&"John Doe"]).expect("Failed to insert data");
|
||||
let id: i32 = rows[0].get(0);
|
||||
|
||||
// Query data
|
||||
let select_query = "SELECT id, name FROM users WHERE id = $1";
|
||||
let row = query_one(select_query, &[&id]).expect("Failed to query data");
|
||||
let name: String = row.get(1);
|
||||
println!("User: {} (ID: {})", name, id);
|
||||
```
|
||||
|
||||
### Connection Management
|
||||
|
||||
The module manages connections automatically, but you can also reset the connection if needed:
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::reset;
|
||||
|
||||
// Reset the PostgreSQL client connection
|
||||
reset().expect("Failed to reset connection");
|
||||
```
|
||||
|
||||
### Builder Pattern
|
||||
|
||||
The module provides a builder pattern for flexible configuration:
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::{PostgresConfigBuilder, with_config};
|
||||
|
||||
// Create a configuration builder
|
||||
let config = PostgresConfigBuilder::new()
|
||||
.host("db.example.com")
|
||||
.port(5432)
|
||||
.user("postgres")
|
||||
.password("secret")
|
||||
.database("mydb")
|
||||
.application_name("my-app")
|
||||
.connect_timeout(30)
|
||||
.ssl_mode("require");
|
||||
|
||||
// Connect with the configuration
|
||||
let client = with_config(config).expect("Failed to connect");
|
||||
```
|
||||
|
||||
### PostgreSQL Installer
|
||||
|
||||
The package includes a PostgreSQL installer that can set up PostgreSQL using nerdctl containers:
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::{PostgresInstallerConfig, install_postgres};
|
||||
|
||||
// Create installer configuration
|
||||
let config = PostgresInstallerConfig::new()
|
||||
.container_name("my-postgres")
|
||||
.version("15")
|
||||
.port(5433)
|
||||
.username("myuser")
|
||||
.password("mypassword")
|
||||
.data_dir("/path/to/data")
|
||||
.persistent(true);
|
||||
|
||||
// Install PostgreSQL
|
||||
let container = install_postgres(config).expect("Failed to install PostgreSQL");
|
||||
```
|
||||
|
||||
### Rhai Integration
|
||||
|
||||
The package provides Rhai scripting support for PostgreSQL operations:
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::rhai::register_postgresclient_module;
|
||||
use rhai::Engine;
|
||||
|
||||
let mut engine = Engine::new();
|
||||
register_postgresclient_module(&mut engine).expect("Failed to register PostgreSQL module");
|
||||
|
||||
// Now you can use PostgreSQL functions in Rhai scripts
|
||||
let script = r#"
|
||||
// Connect to PostgreSQL
|
||||
let connected = pg_connect();
|
||||
|
||||
// Execute a query
|
||||
let rows_affected = pg_execute("CREATE TABLE test (id SERIAL PRIMARY KEY, name TEXT)");
|
||||
|
||||
// Query data
|
||||
let results = pg_query("SELECT * FROM test");
|
||||
"#;
|
||||
|
||||
engine.eval::<()>(script).expect("Failed to execute script");
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environment Variables
|
||||
|
||||
The module uses the following environment variables for configuration:
|
||||
|
||||
- `POSTGRES_HOST`: PostgreSQL server host (default: localhost)
|
||||
- `POSTGRES_PORT`: PostgreSQL server port (default: 5432)
|
||||
- `POSTGRES_USER`: PostgreSQL username (default: postgres)
|
||||
- `POSTGRES_PASSWORD`: PostgreSQL password
|
||||
- `POSTGRES_DB`: PostgreSQL database name (default: postgres)
|
||||
|
||||
### Connection String
|
||||
|
||||
The connection string is built from the configuration options:
|
||||
|
||||
```
|
||||
host=localhost port=5432 user=postgres dbname=postgres
|
||||
```
|
||||
|
||||
With authentication:
|
||||
|
||||
```
|
||||
host=localhost port=5432 user=postgres password=secret dbname=postgres
|
||||
```
|
||||
|
||||
With additional options:
|
||||
|
||||
```
|
||||
host=localhost port=5432 user=postgres dbname=postgres application_name=my-app connect_timeout=30 sslmode=require
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
### Connection Functions
|
||||
|
||||
- `get_postgres_client() -> Result<Arc<PostgresClientWrapper>, PostgresError>`: Get the PostgreSQL client instance
|
||||
- `reset() -> Result<(), PostgresError>`: Reset the PostgreSQL client connection
|
||||
|
||||
### Query Functions
|
||||
|
||||
- `execute(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<u64, PostgresError>`: Execute a query and return the number of affected rows
|
||||
- `query(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Vec<Row>, PostgresError>`: Execute a query and return the results as a vector of rows
|
||||
- `query_one(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Row, PostgresError>`: Execute a query and return a single row
|
||||
- `query_opt(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Option<Row>, PostgresError>`: Execute a query and return an optional row
|
||||
|
||||
### Configuration Functions
|
||||
|
||||
- `PostgresConfigBuilder::new() -> PostgresConfigBuilder`: Create a new PostgreSQL configuration builder
|
||||
- `with_config(config: PostgresConfigBuilder) -> Result<Client, PostgresError>`: Create a new PostgreSQL client with custom configuration
|
||||
|
||||
## Error Handling
|
||||
|
||||
The module uses the `postgres::Error` type for error handling:
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::{query, query_one};
|
||||
|
||||
// Handle errors
|
||||
match query("SELECT * FROM users", &[]) {
|
||||
Ok(rows) => {
|
||||
println!("Found {} users", rows.len());
|
||||
},
|
||||
Err(e) => {
|
||||
eprintln!("Error querying users: {}", e);
|
||||
}
|
||||
}
|
||||
|
||||
// Using query_one with no results
|
||||
match query_one("SELECT * FROM users WHERE id = $1", &[&999]) {
|
||||
Ok(_) => {
|
||||
println!("User found");
|
||||
},
|
||||
Err(e) => {
|
||||
eprintln!("User not found: {}", e);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Thread Safety
|
||||
|
||||
The PostgreSQL client module is designed to be thread-safe. It uses `Arc` and `Mutex` to ensure safe concurrent access to the client instance.
|
||||
|
||||
## Examples
|
||||
|
||||
### Basic CRUD Operations
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::{execute, query, query_one};
|
||||
|
||||
// Create
|
||||
let create_query = "INSERT INTO users (name, email) VALUES ($1, $2) RETURNING id";
|
||||
let rows = query(create_query, &[&"Alice", &"alice@example.com"]).expect("Failed to create user");
|
||||
let id: i32 = rows[0].get(0);
|
||||
|
||||
// Read
|
||||
let read_query = "SELECT id, name, email FROM users WHERE id = $1";
|
||||
let row = query_one(read_query, &[&id]).expect("Failed to read user");
|
||||
let name: String = row.get(1);
|
||||
let email: String = row.get(2);
|
||||
|
||||
// Update
|
||||
let update_query = "UPDATE users SET email = $1 WHERE id = $2";
|
||||
let affected = execute(update_query, &[&"new.alice@example.com", &id]).expect("Failed to update user");
|
||||
|
||||
// Delete
|
||||
let delete_query = "DELETE FROM users WHERE id = $1";
|
||||
let affected = execute(delete_query, &[&id]).expect("Failed to delete user");
|
||||
```
|
||||
|
||||
### Transactions
|
||||
|
||||
Transactions are not directly supported by the module, but you can use the PostgreSQL client to implement them:
|
||||
|
||||
```rust
|
||||
use sal_postgresclient::{execute, query};
|
||||
|
||||
// Start a transaction
|
||||
execute("BEGIN", &[]).expect("Failed to start transaction");
|
||||
|
||||
// Perform operations
|
||||
let insert_query = "INSERT INTO accounts (user_id, balance) VALUES ($1, $2)";
|
||||
execute(insert_query, &[&1, &1000.0]).expect("Failed to insert account");
|
||||
|
||||
let update_query = "UPDATE users SET has_account = TRUE WHERE id = $1";
|
||||
execute(update_query, &[&1]).expect("Failed to update user");
|
||||
|
||||
// Commit the transaction
|
||||
execute("COMMIT", &[]).expect("Failed to commit transaction");
|
||||
|
||||
// Or rollback in case of an error
|
||||
// execute("ROLLBACK", &[]).expect("Failed to rollback transaction");
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
The module includes comprehensive tests for both unit and integration testing:
|
||||
|
||||
```rust
|
||||
// Unit tests
|
||||
#[test]
|
||||
fn test_postgres_config_builder() {
|
||||
let config = PostgresConfigBuilder::new()
|
||||
.host("test-host")
|
||||
.port(5433)
|
||||
.user("test-user");
|
||||
|
||||
let conn_string = config.build_connection_string();
|
||||
assert!(conn_string.contains("host=test-host"));
|
||||
assert!(conn_string.contains("port=5433"));
|
||||
assert!(conn_string.contains("user=test-user"));
|
||||
}
|
||||
|
||||
// Integration tests
|
||||
#[test]
|
||||
fn test_basic_postgres_operations() {
|
||||
// Skip if PostgreSQL is not available
|
||||
if !is_postgres_available() {
|
||||
return;
|
||||
}
|
||||
|
||||
// Create a test table
|
||||
let create_table_query = "CREATE TEMPORARY TABLE test_table (id SERIAL PRIMARY KEY, name TEXT)";
|
||||
execute(create_table_query, &[]).expect("Failed to create table");
|
||||
|
||||
// Insert data
|
||||
let insert_query = "INSERT INTO test_table (name) VALUES ($1) RETURNING id";
|
||||
let rows = query(insert_query, &[&"test"]).expect("Failed to insert data");
|
||||
let id: i32 = rows[0].get(0);
|
||||
|
||||
// Query data
|
||||
let select_query = "SELECT name FROM test_table WHERE id = $1";
|
||||
let row = query_one(select_query, &[&id]).expect("Failed to query data");
|
||||
let name: String = row.get(0);
|
||||
assert_eq!(name, "test");
|
||||
}

//! SAL PostgreSQL Client
|
||||
//!
|
||||
//! This crate provides a PostgreSQL client for interacting with PostgreSQL databases.
|
||||
//! It offers connection management, query execution, and a builder pattern for flexible configuration.
|
||||
//!
|
||||
//! ## Features
|
||||
//!
|
||||
//! - **Connection Management**: Automatic connection handling and reconnection
|
||||
//! - **Query Execution**: Simple API for executing queries and fetching results
|
||||
//! - **Builder Pattern**: Flexible configuration with authentication support
|
||||
//! - **Environment Variable Support**: Easy configuration through environment variables
|
||||
//! - **Thread Safety**: Safe to use in multi-threaded applications
|
||||
//! - **PostgreSQL Installer**: Install and configure PostgreSQL using nerdctl
|
||||
//! - **Rhai Integration**: Scripting support for PostgreSQL operations
|
||||
//!
|
||||
//! ## Usage
|
||||
//!
|
||||
//! ```rust,no_run
|
||||
//! use sal_postgresclient::{execute, query, query_one};
|
||||
//!
|
||||
//! fn main() -> Result<(), Box<dyn std::error::Error>> {
|
||||
//! // Execute a query
|
||||
//! let rows_affected = execute("CREATE TABLE users (id SERIAL PRIMARY KEY, name TEXT)", &[])?;
|
||||
//!
|
||||
//! // Query data
|
||||
//! let rows = query("SELECT * FROM users", &[])?;
|
||||
//!
|
||||
//! // Query single row
|
||||
//! let row = query_one("SELECT * FROM users WHERE id = $1", &[&1])?;
|
||||
//!
|
||||
//! Ok(())
|
||||
//! }
|
||||
//! ```
