What it is

hyper is a low-level, high-performance HTTP/1 and HTTP/2 library for Rust with an asynchronous design built on tokio. It provides both client and server APIs and emphasizes correctness and production-ready performance, serving as the foundational HTTP transport layer for higher-level frameworks like Axum and reqwest. Modular library structure: src/ contains core HTTP logic split into client and server submodules, benches/ includes real-world performance tests (connect.rs, end_to_end.rs, pipeline.rs), examples/ shows usage patterns (client.rs, echo.rs, graceful_shutdown.rs), and capi/ provides a C FFI binding layer for non-Rust consumers via cbindgen.

Start here

Open these first:

• src/lib.rs — Main entry point and public API surface exposing Client, Server, Body, Request/Response types, and feature gates.
• src/client/mod.rs — Client connection management and request dispatch logic; required reading for anyone building HTTP client functionality.
• src/body/mod.rs — Core Body abstraction handling streaming payloads; critical for understanding request/response payload handling.
• src/proto/h1/conn.rs — HTTP/1 connection state machine implementation; foundational for understanding protocol-level framing.
• src/client/conn/http2.rs — HTTP/2 multiplexing and stream management; essential for HTTP/2 protocol knowledge.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/hyperium/hyper.git
cd hyper
cargo build
cargo test
cargo run --example client

Optionally install Rust 1.63+ via rustup if needed.

Daily commands:

cargo build
cargo test                    # Run test suite
cargo bench                   # Run benchmarks in benches/
cargo run --example client    # Run the client example
cargo run --example echo      # Run the echo server example

Set RUST_LOG=debug for tracing output if tracing feature enabled.

Key cautions & unknowns

• Feature flags required: HTTP/2 support is behind the 'http2' feature flag and requires h2 crate—must enable explicitly in Cargo.toml or via cargo build --features http2. Async runtime locked: tokio is…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
