URL: https://github.com/apache/avro/pull/1602#issuecomment-1070235112


   Hey! Pushed some changes to remove the panics from the encode flow plus 
refactored the naming to match the other modules. Found some other future work 
that is relevant and related but in the interest avoiding scope creep I want to 
get some buy-in before I proceed.
   
   Things that can be added to this PR that are significant:
   -  Value Resolution flow has the same schema lookup strategy as the 
encoding, decoding, and parsing flows, which means it has the same potential 
namespacing issues. The flow can be changed to match the others. Better finding 
this now rather than later 🙃 
   - Add in encoded size to the Ok() return from encode. This was discussed but 
would be a lot of code change not related to the original encoding panic bug 
that led to this PR. 
   
   
   I also added in more future work and breaking change (slight) to the PR's 
description.

> After a recent bug regarding Rust Avro's schema ref was fixed to help 
> preserve the parsing form of schema 
> (https://issues.apache.org/jira/browse/AVRO-3433). This exposed an issue 
> where named schemas defined with the rules of the spec (depth first, left to 
> right), are not available to the encoding workflow because it indexes schemas 
> as it traverses the data. This is a problem for the common use case of 
> defining a record within an optional field and it being encoded as Null, and 
> not having that type then available during encoding for the next field. 
>  
> This was patched for level + 1 schema definitions but was not solved within 
> the fullness of the spec
