The library offers an HTTP client built on the hyper library.īy default, reqwest includes a client that’s capable of making asynchronous requests.
If you’re looking for a more high-level HTTP client, reqwest may suit your needs. All-time downloads on crates.io: 12,714,705.Leading in performance through concurrency support.Here’s an overview of hyper’s advantages: Next, use the new await syntax Rust supports to await the response. First, create a new client object, then pass it a URL from which to retrieve data.

Here’s how to make a GET request using reqwest. A deeper level of details can be found in the API reference - e.g., how the Body object is implemented. The official website offers several to help you get started quickly with running an HTTP client or server. Moreover, hyper hosts a pretty active community of contributors and even runs a Discord server. If you want a more convenient HTTP client, hyper recommends checking out reqwest since it’s built on top of hyper (more on this later). Hyper is meant to be a building block for other libraries and applications. If you don’t need any of the advanced features hyper offers, it may be worth checking out a more high-level library based on hyper.

It’s asynchronous by design and offers both client- and server-side APIs. Several of the libraries we’ll discuss in this article are based on hyper. It’s relatively low-level, so it’s perfect for when you need more advanced functionalities. When the high-level libraries don’t offer all the functionalities you’re looking for, it might be a good idea to look into the hyper library. Recent downloads (last 90 days): 379,320.All-time downloads on crates.io: 3,115,828.Let mut data = "this is the body".as_bytes() Įasy.post_field_size(data.len() as u64).unwrap() Here’s an example of a POST request using curl-rust. There are more lightweight solutions out there that provide more tailored features for today’s web needs. curl-rust comes packed with functionalities you don’t always need, like support for transfer protocols such as Telnet, SMTP, FTP, IMAP, or LDAP. My advice is to only use this library if you actually need to use curl - for instance, if you’re working on a project that depends on a diverse tech stack and has already integrated curl. Importantly, this library does not offer any support for asynchronous requests, meaning it’s slower and more resource-heavy than any of its asynchronous counterparts. If you want to completely remain in the realm of Rust and avoid the problems that C-based curl can produce, you may want to opt for one of the libraries that completely rely on Rust. In other words, you can use the functionality of libcurl with an additional layer of security provided by Rust. curl-rustĬurl-rust offers libcurl bindings for Rust, meaning it includes an interface for the C-based HTTP library. We’ll also demonstrate how to make GET and POST requests with each library. In this guide, we’ll walk through the main features of six Rust HTTP clients: Depending on the tech stack your project is built on or the number of HTTP calls you have to make, certain libraries will suit you well while others could be more trouble than they’re worth. It’s impossible to overstate the importance of HTTP clients, which is why you should do your homework when choosing the right HTTP client for your task at hand.
