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.

Hi @gklijs I found more things. On my MacBook Pro (64 GB memory), I remember this issue happened a few times in the past. But now even I have 3000 temperature fields in Confluent Schema Registry, the code still runs well.
On another Linux machine (64 GB memory), this issue consistently shows up when I have 500 temperature fields (less fields like 400 temperature fields, the code works well).

How can I print out stack trace?
I tried to follow https://stackoverflow.com/a/71731489/2000548 adding

use std::env;
fn main() {
  env::set_var("RUST_BACKTRACE", "1");
  // My rest of code
}

and then run cargo run.

Or RUST_BACKTRACE=1 cargo run, but still just print the error

thread 'main' has overflowed its stack
fatal runtime error: stack overflow
Aborted (core dumped)

I'm not sure, likely because the error is kind of outside the reach of Rust, it might not work in this case, which makes it hard to find out where it's going wrong. Googled a bit and it seems to be hard, How to diagnose a stack overflow issue’s cause? but there are some suggestions.
