Allen George commented on THRIFT-2945:
--------------------------------------
[~prz] - let me try to address these points individually.
# "Split the {{read_from_in_protocol}} and {{write_to_out_protocol}} as a
trait." This seems like a great idea. Perhaps it could be named {{TThriftType}}
to keep with the existing naming convention? I suggest submitting this as a PR
since it would be small and self-contained.
# "Auto-derive hash on generated types." Are you sure this works with types
that contain {{OrderedFloat}}? Thrift doubles (represented in Rust by floats,
not fixed-point integers) are the reason why I had to use {{BTreeMap}} and
{{BTreeSet}}, and was unable to auto-derive {{Hash}}. Perhaps I overlooked
something?
# Could you clarify why you need to change the enum and union code-generation?
From what I understand, your main requirement was getting a list of all defined
enum variants and associated values. Since we know the full list of variants
ahead from the thrift file we could simply add a {{values()}} method that
returns the information you need. Also note that I specifically opted *not* to
use generate macros since it adds another level of indirection that anybody
debugging thrift auto-gen code would have to reason about: they'd have to
understand how the thrift gets turned into a macro, the macro definition, and
then the final rust output.
# Finally, while I understand that you want to use the Thrift {{namespace}}
directive. Could you give me a concrete example of what you expect the output
to be? Would it be output to different directories, or would you output it to
the same directory and then rely on a manual step afterwards to move it to the
appropriate Rust module. (PS. Your patch has a bug: you forgot to
{{rust_safe_case}} the module name, and it will break on thrift modules that
already have underscores in them)
Another points: I looked at your branch, and noticed that your formatting is
inconsistent with the existing code (the existing code uses 2-space tabs).
