Expand description

The Wasm code of a Substrate runtime.

Fields

code_fetcher: &'a dyn FetchRuntimeCode

The code fetcher that can be used to lazily fetch the code.

heap_pages: Option<u64>

The optional heap pages this code should be executed with.

If None are given, the default value of the executor will be used.

hash: Vec<u8>

The SCALE encoded hash of code.

The hashing algorithm isn’t that important, as long as all runtime code instances use the same.

Implementations

Create an empty instance.

This is only useful for tests that don’t want to execute any code.
