siodb_driver 0.6.5

# 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_driver = "*"
```

## Quick setup

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

```bash
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

```rust
    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

    siodb_conn.close().unwrap();

## URI

To identify a Siodb resource, the driver use the
[URI format](https://en.wikipedia.org/wiki/Uniform_Resource_Identifier).

For TLS connection (default):

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

For TCP plain text connection:

```
siodb://root@unix_socket?identity_file=/home/siodb/.ssh/id_rsa
```

For Unix socket connection:

```
siodbu://root@unix_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.
- unix_socket: indicate the path of the Unix socket used by Siodb to connect locally.
- trace: to trace everything within the driver to sdtout.
