> I'm implementing the iceberg-rust now and we use the avro-rust to write the
> manifest file. [In iceberg spec, the uuid is the logical type of
> fixed|https://iceberg.apache.org/spec/#avro:~:text=%7B%20%22type%22%3A%20%22fixed%22%2C%0A%C2%A0%C2%A0%22size%22%3A%2016%2C%0A%C2%A0%C2%A0%22logicalType%22%3A%20%22uuid%22%20%7D]
> rather than string as avro spec. So I need to customize the logical type
> using attributes of the schema. But I find that in avro-rust, the attribute
> of schema will be ignore when serialize. Like:

> I'm curious why they are ignored and would it be possible to support
> serializing them so that the user can custom their logical type?
