Rust (Core)

Redlite is written in Rust. You can use it directly as a Rust crate.

Installation

Add to your Cargo.toml:

[dependencies]
redlite = "0.1"

Quick Start

use redlite::Db;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Open in-memory database
    let db = Db::open_memory()?;

    // Or file-based
    let db = Db::open("/path/to/db.db")?;

    // String operations
    db.set("key", b"value")?;
    let val = db.get("key")?;
    println!("{}", String::from_utf8_lossy(&val.unwrap()));

    // Hash operations
    db.hset("user:1", "name", b"Alice")?;
    db.hset("user:1", "age", b"30")?;
    let user = db.hgetall("user:1")?;

    // List operations
    db.lpush("queue", &[b"job1", b"job2"])?;
    let job = db.rpop("queue")?;

    // Set operations
    db.sadd("tags", &[b"redis", b"sqlite"])?;
    let members = db.smembers("tags")?;

    // Sorted sets
    db.zadd("scores", &[(100.0, b"player1"), (85.0, b"player2")])?;
    let top = db.zrevrange("scores", 0, 9)?;

    Ok(())
}
