pub fn validate_updatable_section(
section: &str,
schema: &TypeDefinition,
) -> Result<(), ValidationError>Expand description
Reject an memstead_update attempt to write a section that is either
the virtual relationships surface (managed by memstead_relate) or
not part of the type’s updatable_fields allowlist. When the
allowlist is empty the section passes — types that opt out of the
allowlist accept any declared section.
