pub struct LashCoreBuilder { /* private fields */ }

Implementations

impl LashCoreBuilder

pub fn protocol_plugin(self, plugin: Arc<dyn PluginFactory>) -> Self

pub fn provider(self, provider: ProviderHandle) -> Self

pub fn model(self, model: ModelSpec) -> Self

pub fn max_turns(self, max_turns: usize) -> Self

pub fn session_spec(self, spec: SessionSpec) -> Self

pub fn store_factory(self, store_factory: Arc<dyn SessionStoreFactory>) -> Self

Configure a factory that can create a persistence store for any root session opened from this core.

The factory must honor SessionStoreCreateRequest::session_id and return a store for that specific session. Do not use this to wrap one pre-opened root store; pass root-only stores with LashCore::session(...).store(store) instead.

pub fn child_store_factory( self, store_factory: Arc<dyn SessionStoreFactory>, ) -> Self

Configure the persistence factory used by managed child sessions, such as local subagents.

Child factories must return a distinct store bound to the requested child session id. Hosts that pass an explicit root store with SessionBuilder::store should set this when child sessions need persistence.

pub fn attachment_store( self, attachment_store: Arc<dyn AttachmentStore>, ) -> Self

pub fn process_env_store( self, process_env_store: Arc<dyn ProcessExecutionEnvStore>, ) -> Self

pub fn effect_host(self, effect_host: Arc<dyn EffectHost>) -> Self

Set the deployment effect host — the durability boundary every operation crosses. Pass InlineEffectHost for in-process execution, or a workflow-backed host for durable execution.

pub fn tools(self, tools: Arc<dyn ToolProvider>) -> Self

pub fn plugin(self, plugin: Arc<dyn PluginFactory>) -> Self

pub fn plugins(self, stack: PluginStack) -> Self

pub fn configure_plugins(self, configure: impl FnOnce(&mut PluginStack)) -> Self

pub fn trace_sink(self, trace_sink: Arc<dyn TraceSink>) -> Self

pub fn trace_jsonl_path(self, path: impl Into<PathBuf>) -> Self

pub fn trace_level(self, trace_level: TraceLevel) -> Self

pub fn trace_context(self, trace_context: TraceContext) -> Self

pub fn termination(self, termination: TerminationPolicy) -> Self

pub fn residency(self, residency: Residency) -> Self

pub fn live_replay_store( self, live_replay_store: Arc<dyn LiveReplayStore>, ) -> Self

Configure the bounded live replay buffer used by session observation cursors. This is best-effort reconnect recovery only; durable state still comes from the session store and SessionReadView.

pub fn build(self) -> Result<LashCore>

pub fn advanced(self) -> AdvancedLashCoreBuilder

pub fn process_registry( self, process_registry: Arc<dyn ProcessRegistry>, ) -> Self

pub fn trigger_store(self, store: Arc<dyn TriggerStore>) -> Self

pub fn process_work_driver(self, driver: ProcessWorkDriver) -> Self

Configure an externally owned process work runner.

Durable hosts construct a ProcessWorkDriver from the same process registry and wake handle used by their deployment runner, then pass it here. The driver registry becomes the core’s process registry and no inline runner is spawned.

pub fn queued_work_poke(self, poke: QueuedWorkPoke) -> Self

Wire the wake handle of an externally owned queued-work runner. The runtime pokes it whenever new queued work lands for a session.

Trait Implementations

impl Default for LashCoreBuilder

fn default() -> LashCoreBuilder

Returns the “default value” for a type.

impl PromptLayerSink for LashCoreBuilder

fn prompt_layer_mut(&mut self) -> &mut PromptLayer

Mutable access to the builder’s prompt layer, created on first use.

fn prompt_template(self, template: PromptTemplate) -> Self

Set the base prompt template.

fn prompt_contribution(self, contribution: PromptContribution) -> Self

Add a single prompt contribution to its slot.

fn replace_prompt_slot( self, slot: PromptSlot, contributions: impl IntoIterator<Item = PromptContribution>, ) -> Self

Replace all contributions in a slot.

fn clear_prompt_slot(self, slot: PromptSlot) -> Self

Clear all contributions from a slot.

fn prompt_layer(self, layer: PromptLayer) -> Self

Replace the whole prompt layer.
