------------------------------------

             Summary: Handle null namespace properly
                 Key: AVRO-3812
                 URL: https://issues.apache.org/jira/browse/AVRO-3812
             Project: Apache Avro
          Issue Type: Improvement
          Components: rust
    Affects Versions: 1.12.0
            Reporter: Kousuke Saruta


Considering the following schema, which contains namespaces of "".
{code}
{
 "namespace": "",
 "type": "record",
 "name": "my_schema",
 "fields": [
   {
     "name": "a",
     "type": {
       "type": "enum",
       "name": "my_enum",
       "namespace": "",
       "symbols": ["a", "b"]
     }
   },  {
     "name": "b",
     "type": {
       "type": "fixed",
       "name": "my_fixed",
       "namespace": "",
       "size": 10
     }
   }
 ]
}
{code}

If we try to canonicalize this schema with the following code
{code}
let schema = Schema::parse_str(schema_str).unwrap().canonical_form();
println!("{schema}");
{code}
We get the following result.
{code}
{"name":".my_schema","type":"record","fields":[{"name":"a","type":{"name":".my_enum","type":"enum","symbols":["a","b"]}},{"name":"b","type":{"name":".my_fixed","type":"fixed","size":10}}]}
{code}

But .my_schema, .my_enum and .my_fixed should not starts with a dot.
