denselinkage.serializing.TemplateSerializer

class denselinkage.serializing.TemplateSerializer(template: str, *, column_mapping: Mapping[str, str] | None = None)

Bases: Serializer

"Name: {name}"; column_mapping maps this source’s columns onto the template variables.

Security: template is trusted, developer-supplied configuration. It is rendered with str.format_map over each row, so do not build it from untrusted input — a hostile template could read attributes of the substituted values (the standard str.format injection vector). Field values are only substituted, never parsed, so untrusted row data is safe.
