avro_size_data() to pre-calculate the size of an avro_datum_t in serialized form
--------------------------------------------------------------------------------
Key: AVRO-445
URL: https://issues.apache.org/jira/browse/AVRO-445
Project: Avro
Issue Type: New Feature
Components: c
Affects Versions: 1.3.0
Reporter: Bruce Mitchener
Attachments: avro_size.diff
I would like to be able to find out how much buffer space will be required to
serialize a given avro_datum_t ... I've started implementing this but wanted to
get feedback on the general approach and API.
The details of most of the functions in datum_size.c haven't been updated yet
in the attached patch. The rest should be close to working though.
The main point of concern that I have at the moment is that I'm returning an
int64_t which, if positive, is the length required and if negative, will be an
error condition (like -EINVAL).
Thoughts? Anything else in the attached patch that should change?
