Rust driver for Siodb

A simple driver for Siodb written in pure Rust.

Features

  • Support of URI
  • Connections to Siodb (TLS, TCP, Unix socket)
  • Authentication to Siodb
  • Query execution
  • DML execution

Installation

Add the crate dependency with the version you desire into Cargo.toml:

[dependencies]
siodb = "*"

Quick setup

Start Siodb in a container and get the RSA key for root user locally:

docker run -p 127.0.0.1:50000:50000/tcp --name siodb siodb/siodb
docker exec -it siodb cat /home/siodb/.ssh/id_rsa > ~/root_id_rsa

Example

    let uri = "siodbs://root@localhost:50000?identity_file=/home/nico/root_id_rsa";

    let mut siodb_conn = SiodbConn::new(&uri).expect(&format!("Error connecting to URI '{}'", uri));

    if siodb_conn
        .query_row("select name from sys_databases where name = 'TEST_DB'".to_string())
        .is_none()
    {
        siodb_conn
            .execute("CREATE DATABASE test_db".to_string())
            .expect(&format!("Database creation error."));
    }

    if siodb_conn
        .query_row("select name from test_db.sys_tables where name = 'TEST_TABLE'".to_string())
        .is_none()
    {
        siodb_conn
            .execute(
                "CREATE TABLE test_db.test_table

URI

To identify a Siodb resource, the driver use the URI format.

For TLS connection (default):

siodbs://root@localhost:50000?identity_file=/home/siodb/.ssh/id_rsa

For TCP plain text connection:

siodb://root@localhost:50000?identity_file=/home/siodb/.ssh/id_rsa

For Unix socket connection:

siodbu:/run/siodb/siodb.socket?identity_file=/home/siodb/.ssh/id_rsa

The above example will connect you to the localhost with port number 50000. The driver will do the authentication with the Siodb user root and the identity file /home/siodb/.ssh/id_rsa.

Options

  • identity_file: the path to the RSA private key.
  • trace: to trace everything within the driver to sdtout.
