//! HTTP/1.1 request via the std-blocking [`HttpClientStd`].
//!
//! Requires one of the TLS feature flags (`rustls-ring`, `rustls-aws`
//! or `native-tls`) so the client can open both `http://` and
//! `https://` URLs end-to-end via [`pimalaya_stream`].
//!
//! # Usage
//!
//! ```sh
//! URL=https://example.com/ cargo run --example std_http11
//! ```
