# Interface Errors

Interface errors represent failures surfaced at the public API boundary. `DataDesignerGenerationError` wraps dataset generation failures from `create()` and `preview()`, `DataDesignerEarlyShutdownError` identifies generation runs that terminate early without producing records, and `DataDesignerProfilingError` wraps profiling failures from those methods.

These errors inherit from `data_designer.errors.DataDesignerError`, allowing callers to catch either specific interface failures or the project-wide base error type.
