Overview
Hyper is an asynchronous HTTP library for Rust. It provides HTTP/1 and HTTP/2 client and server APIs and is designed as a lower-level building block for frameworks, clients, gateways, and custom network applications.
Features and best fit

Key features
Handle HTTP/1 and HTTP/2 on both client and server sides
The README highlights HTTP/1, HTTP/2, asynchronous design, and both client and server APIs. Applications can compose connection-level handling and services when they need control below a full web framework.
Sources: [2]
Compose low-level HTTP pieces into servers, proxies, and upgrades
The examples cover basic clients and servers as well as reverse proxies, graceful shutdown, HTTP proxies, upgrades, shared state, and other lower-level patterns.

Best fit
Before adoption
Use a higher-level abstraction when routing or convenience is the main requirement
Hyper's README explicitly describes it as low level and points application-level HTTP clients toward Reqwest and server users toward frameworks such as Axum. Version 1.11.1 also contains several HTTP/1 bug fixes, so patch-level updates remain relevant within the 1.x line.

Supplemental curator note
Hyper is a lower-level HTTP building block rather than a batteries-included web framework or convenience client. Compare Axum for routing-focused servers and Reqwest for application-level HTTP clients before choosing the abstraction layer.
Try it in 3 steps
- 1
Clone the reviewed Hyper release
Clone the reviewed Hyper 1.11.1 tag. A Rust toolchain with Cargo is required.
git clone --depth 1 --branch v1.11.1 https://github.com/hyperium/hyper.git && cd hyper - 2
Start the official hello server
Follow the examples README and run the official hello example with the full feature set. It listens on 127.0.0.1:3000.
cargo run --example hello --features="full" - 3
Check the HTTP response
Send a localhost request from another terminal and confirm that the Hello World response is returned.
curl http://127.0.0.1:3000/
