I getting error while deploying my rust app

 => ERROR [builder 7/9] RUN --mount=type=cache,target=/usr/local/cargo/registry     --mount=type=cache,target=/usr/src/app/target     cargo build --release     36.1s

Process is being SIGKILL’d
This usually points to an OOM kill.

Maybe you’re going over some memory limit?

It was previously working fine, when all the rust files are in single folder. This happened when i tried to separate them into modules.
