Bounded Structured Fields errors, containing no input bytes.

:syntax means malformed wire input; :invalid_value means an invalid value supplied for serialization. :revision_type rejects a type unavailable in the explicitly selected RFC revision; :schema_type rejects a field's disallowed item, inner-list, or parameter type. :limit means a documented bound was exceeded. :invalid_schema and :invalid_limits reject invalid configuration. :invalid_message, :invalid_field, :missing_field, and :unavailable_section identify field capture failures. No partial parse is returned on failure. :duplicate_key means a dictionary key required to be unique (the :unique_keys option of RequestSeal.StructuredFields.parse_field/5, also used by the library's own field policies) repeats before deduplication. :duplicate_parameter rejects repeated parameter names when uniqueness is required (the :unique_parameters option of the same function, also used by the signature parsing policy).
