VedDB Rust Client v0.0.11

Official Rust client library and CLI tool for VedDB Server

This repository provides both a Rust client library and a command-line interface (CLI) for interacting with VedDB Server. Built with async/await and designed for high performance.

What's included:

• 📚 Rust Library (veddb-client) - Async client for embedding in your applications
• 🖥️ CLI Tool (veddb-cli.exe) - Command-line interface for interactive use

✨ Features

• 🚀 Async/Await: Built on Tokio for high-performance async I/O
• 🔌 Connection Pooling: Efficient connection management
• 📝 CLI Tool: Easy-to-use command-line interface
• 🎯 Type-Safe: Full Rust type safety and error handling
• 📊 Multiple Output Formats: Table, JSON, and raw output
• ⚡ Fast: Sub-millisecond operation latency

🚀 Quick Start

Download & Installation (Windows)

VedDB CLI is currently tested and supported on Windows. You can download the pre-built executable:

Option 1: Download from Website

• Visit our website and download the latest Windows CLI .exe

Option 2: GitHub Releases

• Go to Releases
• Download veddb-cli-v0.0.11-windows.exe

Basic Usage

# Ping the server
veddb-cli.exe ping

# Set a key-value pair
veddb-cli.exe kv set name "John Doe"

# Get a value
veddb-cli.exe kv get name

# List all keys
veddb-cli.exe kv list

# Delete a key
veddb-cli.exe kv del name

📖 CLI Commands

Global Options

veddb-cli.exe [OPTIONS] <COMMAND>

Options:
  -s, --server <SERVER>  Server address [default: 127.0.0.1:50051]
  -f, --format <FORMAT>  Output format [default: table] [values: table, json, raw]
  -v, --verbose          Enable verbose output
  -h, --help             Print help
  -V, --version          Print version

KV Commands

Set a Key

veddb-cli.exe kv set <KEY> <VALUE>

Examples:
veddb-cli.exe kv set name "Alice"
veddb-cli.exe kv set age 25
veddb-cli.exe kv set city "New York"

Get a Key

veddb-cli.exe kv get <KEY>

Example output:
+------+-------+
| Key  | Value |
+------+-------+
| name | Alice |
+------+-------+

Delete a Key

veddb-cli.exe kv del <KEY>

List All Keys

veddb-cli.exe kv list

Example output:
+------+
| Keys |
+------+
| name |
| age  |
| city |
+------+

Ping Command

Check server connectivity:

veddb-cli.exe ping

Example output:
+--------+---------+
| Status | Latency |
+--------+---------+
| pong   | 0 ms    |
+--------+---------+

Output Formats

Table Format (Default)

veddb-cli.exe kv get name

JSON Format

veddb-cli.exe -f json kv get name

Raw Format

veddb-cli.exe -f raw kv get name

🔧 Using as a Library

Add to your Cargo.toml:

[dependencies]
veddb-client = "0.0.11"
tokio = { version = "1", features = ["full"] }

Basic Example

use veddb_client::Client;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Connect to server
    let client = Client::connect("127.0.0.1:50051").await?;
    
    // Ping server
    client.ping().await?;
    println!("Server is alive!");
    
    // Set a key
    client.set("name", "Alice").await?;
    
    // Get a key
    let value = client.get("name").await?;
    println!("Value: {}", String::from_utf8_lossy(&value));
    
    // List all keys
    let keys = client.list_keys().await?;
    println!("Keys: {:?}", keys);
    
    // Delete a key
    client.delete("name").await?;
    
    Ok(())
}

Connection Pooling

use veddb_client::Client;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create client with connection pool
    let client = Client::with_pool_size("127.0.0.1:50051", 10).await?;
    
    // Use client (connections are automatically managed)
    client.set("key", "value").await?;
    
    Ok(())
}

🛠️ Development

Building from Source

Prerequisites:

• Rust 1.75 or later (Install Rust)
• Windows 10/11

git clone https://github.com/Mihir-Rabari/ved-db-rust-client.git
cd ved-db-rust-client
cargo build --release

CLI binary will be at: target\release\veddb-cli.exe

Running Tests

cargo test

Building Just the CLI

cargo build --release --bin veddb-cli

📊 Performance

• Latency: < 1ms for most operations
• Connection Pooling: Reuses connections for better performance
• Async I/O: Non-blocking operations with Tokio

🔌 Protocol Details

The client implements the VedDB binary protocol:

• Little-endian encoding for all integers
• Command format: 24-byte header + payload
• Response format: 20-byte header + payload
• Automatic retries: On connection failures
• Timeout handling: Configurable request timeouts
