Connecting to a database in Rust

Enable the feature for your database engine on the alphadb crate. In this example we’ll use PostgreSQL.

[dependencies]
alphadb = { version = "...", features = ["postgres"] }

Import AlphaDB and the engines module.

use alphadb::AlphaDB;
use alphadb::engine;

Create an instance with the engine’s runtime config and connect it to a database using your credentials.

let mut db = AlphaDB::new(engine::postgres());
 
match db.connect("host", "user", "password", "database", 5432) {
	Ok(_) => println!("Connected!"),
	Err(e) => eprintln!("Connection attempt failed: {}", e.message)
}

To connect to MySQL instead, enable the mysql feature and use engine::mysql(), with the matching port (usually 3306).

Replace the credentials with your own. AlphaDB requires the user to have the following privileges: CREATE, INSERT, DELETE, SELECT, UPDATE, ALTER, DROP and REFERENCES.
