support of namespace field

[untereiner]

Hi,

I have a bunch an .avpr file (or a bunch of .avsc files) for whom I want to generate rust traits. These schemas are organized into namespaces.
I would like to give a try to implement a possible solution. I though about modules but I am beginner in rust. Do you think it could be a good solution to organize the files and the code into a crate ?

I think it might be possible to have rust modules corresponding to avro namespaces.

It could be within a single file or split in multiple files, although a single file sounds better to me.

I think the tricky point to add namespaces with the current implementation is that namespaces might change how the dependency order/dag is calculated (since you would need to group all structs from a same namespace together when generating it).

In any case it will be better to give it a try after the latest official avro-rs is released and integrated to this crate.

yes what's true.
I will give it a try when rsgen-avro has officially moved to the apache-avro rust implementation.

I made a PR #79 for adding the sanitized namespace as a prefix to the generated type. This allows for having schemas with multiple namespaces and colliding record/field names to coexist.
It results in quite long names, however is significantly easier to implement than splitting the types into separate modules without messing up the dependency tree.
