#  `-Awarnings` allows all warnings, for cleaner output (warnings should be detected in aw-server-rust CI anyway)
#  `-C debuginfo=2` is to keep debug symbols, even in release builds (later stripped by gradle on production builds, non-stripped versions needed for stack resymbolizing with ndk-stack)
#  `-g` is to keep debug symbols in the build, bloats the binary from 7M -> 60MB. Currently using profile.release.debug in Cargo.toml however as -g didn't work on the first try
