//! The 6-dimension Rust messaging framework.
//!
//! Hexeract is an opinionated messaging framework for Rust. It unifies
//! in-process mediator dispatch, multi-broker transport, transactional
//! outbox, sagas, scheduler and request/reply in a single ergonomic crate.
//!
//! This crate is a placeholder. The full implementation ships in v0.1.0.
//!
//! # Features (coming in v0.1.0)
//!
//! - **Mediator**: typed command dispatch with zero runtime reflection
//! - **Bus**: unified transport for RabbitMQ, NATS, Kafka, SQS
//! - **Outbox**: transactional outbox/inbox pattern over sqlx
//! - **Sagas**: stateful long-running workflow orchestration
//! - **Scheduler**: delayed and cron-scheduled messages
//! - **Request/Reply**: synchronous RPC over async bus via correlation IDs
