## Pydantic models

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> is a Python library to perform data validation.

You declare the "shape" of the data as classes with attributes.

And each attribute has a type.

```

The server address variable is _required_. TLS is assumed to be on by default. The port in the server address is optional and defaults to 636 if not provided.

**MinIO sends LDAP credentials to the LDAP server for validation. So we _strongly recommend_ to use MinIO with AD/LDAP server over TLS or StartTLS _only_. Using plain-text connection between MinIO and LDAP server means _credentials can be compromised_ by anyone listening to network traffic.**

	BatchJobExpireObject string = "object"
	// BatchJobExpireDeleted - delete marker type
	BatchJobExpireDeleted string = "deleted"
)

// Validate returns nil if ef has valid fields, validation error otherwise.
func (ef BatchJobExpireFilter) Validate() error {
	switch ef.Type {
	case BatchJobExpireObject:
	case BatchJobExpireDeleted:
		if len(ef.Tags) > 0 || len(ef.Metadata) > 0 {

}

// ReplicationPermissionCheck - Check if error type is ReplicationPermissionCheck.
type ReplicationPermissionCheck struct{}

func (e ReplicationPermissionCheck) Error() string {
	return "Replication permission validation requests cannot be completed"
}

func isReplicationPermissionCheck(err error) bool {
	_, ok := err.(ReplicationPermissionCheck)
	return ok
}

		header: h,
		zipw:   w.cw,
	}
	w.last = fw
	return fw, nil
}

// Copy copies the file f (obtained from a [Reader]) into w. It copies the raw
// form directly bypassing decompression, compression, and validation.
func (w *Writer) Copy(f *File) error {
	r, err := f.OpenRaw()
	if err != nil {
		return err
	}
	// Copy the FileHeader so w doesn't store a pointer to the data
	// of f's entire archive. See #65499.

  | o add specification element to a field, this would be more a technical description of
  |   what is allowed in the field.
  |
  | o validators: there could be several levels of validation. Simple type validation could
  |   be done with a regex, but we need inter-field validation and rules which could be
  |   dealt with by something like drools.

  | o i18n: would be good to be able to have names/descriptions/specifications
