Module host_fn 

Host functions used to spawn and call into PolkaVM instances.

Use crate::Virt instead of these raw host functions. This will also make sure that everything works when running the code in native (test code) as this is a wasm_only interface.

⚠️ Unstable — Do Not Use in Production ⚠️

This interface is unstable and subject to breaking changes without notice.

These host functions are not available on Polkadot (or any other production relay/parachain) until the API has been stabilized. If you use them in a production runtime, your runtime will break when the API changes.

Only use for local testing, development, and experimentation on test networks. There is no stability guarantee and no deprecation period.
