Description

The specification says about the name and namespace like as follows.

The empty string may also be used as a namespace to indicate the null namespace

If the name specified contains a dot, then it is assumed to be a fullname, and any namespace also specified is ignored

According to this specification, if a name in a name field starts with a dot, it's considered that the namespace is null and the corresponding namespace field should be ignored.

For example, given the following schema.

{
  "name":  ".record1",
  "namespace": "ns1",
  "type": "record",
  "fields": []
}

The name and namespace should be "record1" and null respectively.
But the namespace is considered as "ns1" in the current Rust binding .
