V2/ue/Build/Rust/v2-rust-cross-compilation.json defines cross-compilation support for Linux server binaries from macOS and Windows hosts plus WASM output targets. The companion Cargo config is V2/ue/Build/Rust/cargo-cross-config.toml.

Linux server targets use cargo zigbuild with Zig linkers for x86_64-unknown-linux-gnu and aarch64-unknown-linux-gnu. This lets macOS and Windows build agents produce Linux server artifacts for packages such as egbe-world-server, egbe-realtime-gateway, moremi-realm-server, and danu-mesh-cluster.

WASM targets cover wasm32-unknown-unknown, wasm32-wasip1, and wasm32-wasip2. WASM package plans include browser/runtime-facing crates such as maya-plugin-api, neith-runtime, and v7-dev-hygiene.

The planner is:

bash
python3 V2/ue/Tools/plan-v2-rust-cross-compile.py \
  --manifest V2/ue/Build/Rust/v2-rust-cross-compilation.json \
  --json-out /tmp/v2-rust-cross-plan.json

Horde publishes $(ArchiveRoot)/Rust/cross-compilation-plan.json and gates Linux server target coverage with rust-cross-linux-server-plan and WASM target coverage with rust-cross-wasm-target-plan.
