http_wire 0.7.0

//! Example demonstrating synchronous HTTP encoding without requiring an async runtime.
//!
//! This example shows how to use `WireEncode` to encode HTTP requests and responses
//! in a synchronous context (e.g., in a non-async main function or library).
//!
//! Run with: cargo run --example sync_encode
