layer

const layer: (instanceDirectory) => Layer.Layer<CursorStore | CycleBudgets | ItemProjectionReader | ItemProjectionWriter | LoopControl | RepositoryLabelProjectionReader | RepositoryLabelProjectionWriter | RunEngine | RunReader, RunEngineError, StepExecutor | TriggerCondition>

The local runtime on .usine/runtime.sqlite.

Parameters

Parameter	Type
instanceDirectory	InstanceDirectory

Returns

Layer.Layer<CursorStore | CycleBudgets | ItemProjectionReader | ItemProjectionWriter | LoopControl | RepositoryLabelProjectionReader | RepositoryLabelProjectionWriter | RunEngine | RunReader, RunEngineError, StepExecutor | TriggerCondition>

const localSqliteLayer: (instanceDirectory) => Layer.Layer<RunDatabase | SqlClient | SqliteClient.SqliteClient, EnginePersistenceError, never>

Parameters

Parameter	Type
instanceDirectory	InstanceDirectory

Returns

Layer.Layer<RunDatabase | SqlClient | SqliteClient.SqliteClient, EnginePersistenceError, never>

observationLayer

const observationLayer: (instanceDirectory) => Layer.Layer<CycleBudgets | ItemProjectionReader | LoopControl | RepositoryLabelProjectionReader | RunReader, RunEngineError>

Observation services initialize the local database but never recover Runs or start Attempts.

Parameters

Parameter	Type
instanceDirectory	InstanceDirectory

Returns

Layer.Layer<CycleBudgets | ItemProjectionReader | LoopControl | RepositoryLabelProjectionReader | RunReader, RunEngineError>

runReaderLayer

const runReaderLayer: (instanceDirectory) => Layer.Layer<RunReader, EnginePersistenceError>

Opens an existing .usine/runtime.sqlite in SQLite read-only mode, without initializing or migrating the database.

Parameters

Parameter	Type
instanceDirectory	InstanceDirectory

Returns

Layer.Layer<RunReader, EnginePersistenceError>
