Rumbo HTTP Client

A lightweight, minimal HTTP client library for Rust with async support.

Features

• ✅ Minimal dependencies and small binary size
• ✅ Async/await support with tokio
• ✅ GET and POST requests
• ✅ JSON serialization/deserialization support
• ✅ Optional TLS/HTTPS support
• ✅ Simple, intuitive API
• ✅ Proper error handling

Installation

Add this to your Cargo.toml:

[dependencies]
rumbo_http_client = "0.1.0"

# Enable TLS support for HTTPS requests
rumbo_http_client = { version = "0.1.0", features = ["tls"] }

Quick Start

use rumbo_http_client::{HttpClient, HttpMethod};
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // GET request
    let response = HttpClient::fetch(
        HttpMethod::GET,
        "http://httpbin.org/get".to_string(),
        None::<()>,
    ).await?;

    println!("Status: {}", response.status);
    if let Some(body) = response.body {
        println!("Body: {}", body);
    }

    // POST request with JSON
    let data = json!({"key": "value"});
    let response = HttpClient::fetch(
        HttpMethod::POST,
        "http://httpbin.org/post".to_string(),
        Some(data),
    ).await?;

    Ok(())
}

API Reference

HttpClient::fetch()

pub async fn fetch<T: Serialize>(
    method: HttpMethod,
    url: String,
    body: Option<T>
) -> Result<Response, HttpError>

Response

pub struct Response {
    pub status: u16,
    pub headers: HashMap<String, String>,
    pub body: Option<String>,
}

impl Response {
    pub fn is_success(&self) -> bool
    pub fn header(&self, name: &str) -> Option<&String>
}

Features

Default Features

• Basic HTTP support (no TLS)

Optional Features

• tls: Enable HTTPS support using native-tls

Size Optimization

This library is optimized for minimal size:

• Minimal dependencies
• Optional TLS support
• Compile-time optimizations in Cargo.toml
• No unnecessary features

Examples

Run the example:

cargo run --example basic_usage --features tls
