To package a Ruby gem with a Rust native extension, configure Cargo workspace paths alongside Rakefile and extconf.rb build steps, then run rake tasks to compile the extension and generate gem artifacts in pkg/.

Building Rust-backed Ruby gems fails during preflight when Cargo workspace wiring is misconfigured, extconf.rb paths are incorrect, or gemspec validations and versioning conventions miss RubyGems distribution requirements.

The best way to wire a Ruby gem into a Cargo workspace is aligning the gem directory structure with Cargo paths and configuring Rakefile build routines to ensure the native extension compiles within the workspace.

You need rb_sys to build Ruby native extensions with Rust because it provides the cargo integration and build tooling required to compile Magnus-backed Rust code into Ruby gem artifacts.

To validate a Rust native gem before publishing to RubyGems, run release preflight checks to verify versioning, ensure compiled artifacts exist in pkg/, and prepare gem credentials for distribution.
