lash/
lib.rs

1//! App-facing embedding facade for Lash.
2//!
3//! `lash` is intentionally a small layer above the lower-level
4//! `lash-core` runtime crate. Host applications own providers, persistence,
5//! app state, HTTP protocols, auth, and frontend streaming; this crate
6//! owns only the ergonomic core/session/turn API.
7//!
8//! Every public name has exactly one home. The crate root carries the daily
9//! core/session/turn path; each domain module ([`tools`], [`persistence`],
10//! [`plugins`], [`observe`], [`triggers`], ...) carries its own
11//! vocabulary. [`prelude`] mirrors the crate root exactly.
