1//! Shared effectful host orchestration for Everruns execution adapters.
2//!
3//! `everruns-host` sits between the pure `everruns-engine` planner and the
4//! application, worker, and local adapters that apply its effects. It is a
5//! transitive implementation boundary, not the ordinary application
6//! entrypoint; applications in the [Everruns](https://everruns.com) ecosystem
7//! should normally depend on `everruns`.
8//!
9//! The deprecated `everruns-runtime` package re-exports this implementation so
10//! its 0.17 public paths continue to use the same canonical code. Existing
11//! users should follow the [runtime migration guide](https://docs.everruns.com/framework/runtime-compatibility/).
12//!
13//! # Example
14//!
15//! ```
16//! use everruns_host::{RuntimeHostAdapter, RuntimeHostTurnContext};
17//!
18//! fn accepts_host<A: RuntimeHostAdapter>() {}
19//! fn accepts_context(_: RuntimeHostTurnContext) {}
20//! # let _ = accepts_context;
21//! ```
