Rust HTTP client & server libraries

[247arjun]

HTTP client/server code

When scanning .toml files, specifically Cargo.toml files in Rust projects, for dependencies that indicate HTTP usage, I looked for crates that provide HTTP client or server functionalities.

Here are some common dependencies that I encountered when I did this search ~3 years ago (the version numbers are all almost certainly outdated):

HTTP Client Libraries

• reqwest: A popular HTTP client library that provides a convenient, higher-level API for making HTTP requests. It is built on hyper.

  reqwest = "0.11"

• hyper: A fast, low-level HTTP implementation written in Rust. While it can be used directly, it's also a building block for other HTTP clients and servers.

  hyper = "0.14"

• surf: A lightweight, async HTTP client library that is part of the async-std ecosystem.

  surf = "2.2"

• ureq: A simple, blocking HTTP client that is suitable for single-threaded applications.

  ureq = "2.1"

• isahc: A versatile HTTP client with a focus on ease of use and safe defaults.

  isahc = "1.0"

The reqwest library

HTTP Server Libraries:

actix-web

A powerful, pragmatic, and extremely fast web framework for Rust.

actix-web = "3.0"

rocket

A web framework for Rust with a focus on ease-of-use, expressibility, and speed.

Rocket is an async backend web framework for Rust with a focus on usability, security, extensibility, and speed. Rocket makes it simple to write secure web applications without sacrificing productivity or performance.

rocket = "0.4" # 0.5 just released on 17-Nov-2023

• warp: A composable web server framework that leverages the hyper library for underlying HTTP handling.

  warp = "0.3"

• tide: A minimal and pragmatic Rust web application framework built on top of async-std.

  tide = "0.16"

• gotham: A flexible web framework that does not sacrifice safety, security, or speed.

  gotham = "0.5"

HTTP Utilities and Middleware:

• http: Provides types and traits for working with HTTP.

  http = "0.2"

• tower: A library of modular and reusable components for building robust networking clients and servers.

  tower = "0.4"

• tower-http: A collection of middleware and utilities for use with tower and hyper.

  tower-http = "0.1"

Asynchronous Runtimes:

While not HTTP-specific, asynchronous runtimes are often used in conjunction with async HTTP libraries. Look for:

• tokio: A runtime for writing reliable, asynchronous, and slim applications with the Rust programming language.

  tokio = { version = "1.0", features = ["full"] }

• async-std: An async port of the Rust standard library.

  async-std = "1.9"
