Expand description
App-facing embedding facade for Lash.
lash is intentionally a small layer above the lower-level
lash-core runtime crate. Host applications own providers, persistence,
app state, HTTP protocols, auth, and frontend streaming; this crate
owns only the ergonomic core/session/turn API.
Every public name has exactly one home. The crate root carries the daily
core/session/turn path; each domain module (tools, persistence,
plugins, observe, triggers, …) carries its own
vocabulary. prelude mirrors the crate root exactly.

Modules§
- admin
- direct
- durability
- messages
- observe
- Session observation: cursors, resumable event streams, and live replay
recovery for host frontends. Entry point:
LashSession::observe/ObservableSession. - persistence
- plugins
- prelude
- The prelude is exactly the crate root:
use lash::prelude::*;brings in the daily core/session/turn vocabulary and nothing from the domain modules. - process
- prompt
- provider
- remote
- runtime
- scenario_
contracts - tools
- tracing
- triggers
- Triggers and subscriptions: declaring event sources, emitting occurrences,
and inspecting trigger subscriptions. Entry points:
LashCore::triggersandLashSession::triggers. - turn
- usage
- Token usage tracking surfaces.
