rqlite-rs

rqlite-rs is a Rust client for rqlite, the distributed relational database built on SQLite, providing an async interface for seamless integration with Rust's async ecosystems. Utilizing reqwest for efficient connection management, it offers a Rustic, high-level API for easy and efficient interaction with rqlite clusters.

Features

• Asynchronous Interface: Fully async, compatible with Tokio, async-std, and smol.
• Connection Pooling: Efficient management of connections to the rqlite cluster.
• High-Level API: Simplifies interactions with the rqlite API.
• Resilience: Automatic failover to a secondary node on connectivity issues.
• Cluster Management: Full control over the cluster with node query and management features.

Installation

Add to your Cargo.toml:

[dependencies]
...
+ rqlite-rs = "0.3.20"

Quick Start

Ensure you have a running rqlite cluster. Replace localhost:4001 and localhost:4002 with your node addresses:

use rqlite_rs::prelude::*;

#[derive(FromRow)]
pub struct Table {
    name: String,
}

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let client = RqliteClientBuilder::new()
        .known_host("localhost:4001")
        .build()?;

    let query = rqlite_rs::query!(
        "SELECT name FROM sqlite_master WHERE type='table' AND name NOT LIKE 'sqlite_%'"
    )?;

    let rows = client.fetch(query).await?;

    let tables = rows.into_typed::<Table>()?;

    for table in tables {
        println!("Table: {}", table.name);
    }

    Ok(())
}

Resilience

The client supports automatic failover, attempting to connect to the next known node if a connection error or timeout occurs, ensuring high availability.
