Get list of validation results for each rule/check?

Hi,

Would it be possible to add support for returning (optionally) a dictionary or similar structure that maps each rule/check to its ValidationResult instance?

We have a use case for integrating dataframely's schema validation with Dagster asset checks. To enable this, we need a way to programmatically access each rule's validation result so we can dynamically map them to corresponding asset checks.

Currently, the validation output may look like:

ValidationError: 4 rules failed validation:
 - 'reasonable_bathroom_to_bedrooom_ratio' failed for 1 rows
 - 'minimum_zip_code_count' failed for 2 rows
 * Column 'zip_code' failed validation for 1 rules:
   - 'min_length' failed for 1 rows
 * Column 'num_bedrooms' failed validation for 1 rules:
   - 'nullability' failed for 2 rows

Hence, it would be great to have an API to obtain validation results in a structured mapping, e.g.:

{
    "reasonable_bathroom_to_bedrooom_ratio": ValidationResult(...),
    "minimum_zip_code_count": ValidationResult(...),
    "zip_code_min_length": ValidationResult(...),
    ...,
}

This would allow us to:

• Dynamically map each check to a Dagster asset check.
• Retrieve per-rule validation details programmatically, not just from the textual summary.

Thanks! :)

Start by tracing how the current validation output is assembled and where ValidationResult instances are created or retained. Define an optional structured mapping for each rule or check while preserving the existing textual summary, then verify that callers can retrieve per-rule details for Dagster asset checks.
