//! CoW Protocol orderbook DTOs, quote builders, and HTTP client.
//!
//! # HTTP transport
//!
//! The `http-client` feature (enabled by default) gives every
//! constructor a working backend without naming a transport. The
//! ergonomic constructors build over [`DefaultTransport`], a type alias
//! resolved per target: `ReqwestTransport` on native builds and
//! `FetchTransport` (the browser `fetch` global) on `wasm32`. Only one
//! concrete type exists per target, so `ReqwestTransport` is absent on
//! `wasm32` and `FetchTransport` is absent on native; name
//! [`DefaultTransport`] in cross-target code rather than a concrete
//! backend.
//!
//! On native targets `http-client` links `reqwest`; on `wasm32` it
//! links `js-sys`, `wasm-bindgen`, and `wasm-bindgen-futures` and never
//! links `reqwest`. To supply your own backend, implement
//! [`HttpTransport`] and pass it to
//! [`OrderBookApi::new_with_transport`]: the trait itself stays
//! feature-independent, so an out-of-tree backend needs neither
//! `http-client` nor either concrete transport.
