[avro] 01/01: AVRO-3433: Rust: The canonical form should preserve schema references
This is an automated email from the ASF dual-hosted git repository.
mgrigorov pushed a commit to branch avro-3433-preserve-schema-ref-in-json
in repository https://gitbox.apache.org/repos/asf/avro.git
commit 637bd0ed70989021f1cccd6511f4451e44234eaa
Author: Martin Tzvetanov Grigorov <mg...@apache.org>
AuthorDate: Sun Mar 6 15:58:19 2022 +0200
AVRO-3433: Rust: The canonical form should preserve schema references
Do not resolve Schema::Ref when printing as JSON.
The Java SDK complains that a type is redefined if it is not a Ref the
second time
