Validation (Internal)

Job configuration validation now lives in the internal functualize._config/job_config.py module. End users interact with validation through:

• functualize.job.JobConfigView — the public resolved configuration view
• JobConfig Pydantic models — standard Pydantic BaseModel subclasses that are validated automatically

Public API

from functualize.job import JobConfigView

How Validation Works

When a job function declares a Pydantic BaseModel parameter, functualize:

1. Extracts field definitions from the model
2. Resolves values from the config resolution chain (CLI → Env → File → Default)
3. Validates the resolved values against the Pydantic model
4. Raises ValidationError if required fields are missing or types don't match

Internal Location

• _config/job_config.py — JobConfigView implementation + validation logic

Internal API

The validation implementation is in functualize._config. Import from functualize.job for the public JobConfigView type.

See the JobConfig with Pydantic guide for usage details.
