codexwire 0.1.1

//! `codexwire`: a client for `OpenAI` Codex's app-server (`codex app-server`,
//! JSON-RPC over the child's stdio), the Codex counterpart to ccwire.
//!
//! Faithful to Codex's own protocol: [`protocol`] is generated from the
//! pinned Codex's JSON Schema (`scripts/gen-codex-protocol`; the schema and
//! its `VERSION` are in `schema/`, [`CODEX_VERSION`] is the version), [`rpc`]
//! frames its messages, [`client`] runs the child and matches responses to
//! requests, and [`auth`] gives a session its own copy of `auth.json`.
//! [`exec`] runs one-shot `codex exec` jobs in a private `CODEX_HOME`.
//!
//! The README follows (its examples are compiled as doctests).
//!
#![doc = include_str!("../README.md")]
#![deny(rustdoc::broken_intra_doc_links)]
// Owned arguments where the callee keeps them, and Result-returning helpers
// kept uniform; the error docs would only restate the messages.

// `#[tokio::test]` expands to `block_on`, which clippy.toml keeps out of
// the library itself.
