//! This module contains the client implementations for the various HTTP clients.
//!
//! A client must be a (`Service`)[`tower_service::Service`]
//! that receives a [`http::Request<ClientBody>`] and returns a [`http::Response`].
//!
//! This crate provides a default client implementation using [`hyper`].
//!
//! However, you can use any service as a client, and add more layer upon it.
