Got "fatal runtime error: stack overflow" when the schema in Confluent Schema Registry is big

[hongbo-miao]

Describe the bug

When the protobuf schema in Confluent Schema is big, based on my debugging, this step

        let proto_payload = encoder
            .encode(
                &buf,
                "production.iot.Motor",
                SubjectNameStrategy::TopicNameStrategy(topic.to_string(), false),
            )
            .await
            .expect("Failed to encode with schema registry");

will cause the app fail with error:

thread 'main' has overflowed its stack
fatal runtime error: stack overflow

To Reproduce

1. Download the producer code at https://github.com/hongbo-miao/hongbomiao.com/tree/c60ab834456279df00ec55b1e2c7a245df82e277/hm-kafka/kafka-client/kafka-rust/proto-producer

2. Change to 500 temperature fields for Motor in main.rs file:

Expected behavior

I expect the app not crash.

Additional context

If I change to less fields such as 400 temperature fields in Confluent Schema Registry, this line works well and won't crash.

        let proto_payload = encoder
            .encode(
                &buf,
                "production.iot.Motor",
                SubjectNameStrategy::TopicNameStrategy(topic.to_string(), false),
            )
            .await
            .expect("Failed to encode with schema registry");

Can you share the stacktrace please? I wonder if it's an issue with the implementation of logos or something else. maciejhirsz/logos#400 might be related.
