trulens.core.schema.app ¶

Serializable app-related classes.

Classes¶

RecordIngestMode ¶

Bases: str, Enum

Mode of records ingestion.

Specify this using the ingest_mode to App constructors.

Attributes¶

IMMEDIATE `class-attribute` `instance-attribute` ¶

IMMEDIATE = 'immediate'

Each record is ingested one by one and written to the database. This is the default mode.

BUFFERED `class-attribute` `instance-attribute` ¶

BUFFERED = 'buffered'

Records are buffered and ingested in batches to the database.

AppDefinition ¶

Bases: WithClassInfo, SerialModel

Serialized fields of an app here whereas App contains non-serialized fields.

Attributes¶

tru_class_info `instance-attribute` ¶

tru_class_info: Class

Class information of this pydantic object for use in deserialization.

Using this odd key to not pollute attribute names in whatever class we mix this into. Should be the same as CLASS_INFO.

app_id `class-attribute` `instance-attribute` ¶

app_id: AppID = Field(frozen=True)

Unique identifier for this app.

Computed deterministically from app_name and app_version. Leaving it here for it to be dumped when serializing. Also making it read-only as it should not be changed after creation.

app_name `instance-attribute` ¶

app_name: AppName

Name for this app. Default is "default_app".

app_version `instance-attribute` ¶

app_version: AppVersion

Version tag for this app. Default is "base".

metadata `instance-attribute` ¶

metadata: Metadata

Metadata for the app.

feedback_definitions `class-attribute` `instance-attribute` ¶

feedback_definitions: Sequence[FeedbackDefinitionID] = []

Feedback functions to evaluate on each record.

feedback_mode `class-attribute` `instance-attribute` ¶

feedback_mode: FeedbackMode = WITH_APP_THREAD

How to evaluate feedback functions upon producing a record.

root_class `instance-attribute` ¶

root_class: Class

Class of the main instrumented object.

Ideally this would be a ClassVar but since we want to check this without instantiating the subclass of AppDefinition that would define it, we cannot use ClassVar.

root_callable `class-attribute` ¶

root_callable: FunctionOrMethod

App's main method.

This is to be filled in by subclass.

app `instance-attribute` ¶

app: JSONized[AppDefinition]

Wrapped app in jsonized form.

initial_app_loader_dump `class-attribute` `instance-attribute` ¶

initial_app_loader_dump: Optional[SerialBytes] = None

Serialization of a function that loads an app.

Dump is of the initial app state before any invocations. This can be used to create a new session.

Warning

Experimental work in progress.

app_extra_json `instance-attribute` ¶

app_extra_json: JSON

Info to store about the app and to display in dashboard.

This can be used even if app itself cannot be serialized. app_extra_json, then, can stand in place for whatever data the user might want to keep track of about the app.

record_ingest_mode `instance-attribute` ¶

record_ingest_mode: RecordIngestMode = record_ingest_mode

Mode of records ingestion.

tags `instance-attribute` ¶

tags: Tags = tags

Tags for the app.

Functions¶

__rich_repr__ ¶

__rich_repr__() -> Result

Requirement for pretty printing using the rich package.

load `staticmethod` ¶

load(obj, *args, **kwargs)

Deserialize/load this object using the class information in tru_class_info to lookup the actual class that will do the deserialization.

model_validate `classmethod` ¶

model_validate(*args, **kwargs) -> Any

Deserialized a jsonized version of the app into the instance of the class it was serialized from.

Note

This process uses extra information stored in the jsonized object and handled by WithClassInfo.

continue_session `staticmethod` ¶

continue_session(
    app_definition_json: JSON, app: Any
) -> AppDefinition

Instantiate the given app with the given state app_definition_json.

Warning

This is an experimental feature with ongoing work.

PARAMETER	DESCRIPTION
`app_definition_json`	The json serialized app. TYPE: `JSON`
`app`	The app to continue the session with. TYPE: `Any`

RETURNS	DESCRIPTION
`AppDefinition`	A new `AppDefinition` instance with the given `app` and the given `app_definition_json` state.

new_session `staticmethod` ¶

new_session(
    app_definition_json: JSON,
    initial_app_loader: Optional[Callable] = None,
) -> AppDefinition

Create an app instance at the start of a session.

Warning

This is an experimental feature with ongoing work.

Create a copy of the json serialized app with the enclosed app being initialized to its initial state before any records are produced (i.e. blank memory).

get_loadable_apps `staticmethod` ¶

get_loadable_apps()

Gets a list of all of the loadable apps.

Warning

This is an experimental feature with ongoing work.

This is those that have initial_app_loader_dump set.

select_inputs `classmethod` ¶

select_inputs() -> Lens

Get the path to the main app's call inputs.

select_outputs `classmethod` ¶

select_outputs() -> Lens

Get the path to the main app's call outputs.
