How to import WrapDatabaseAsync

[paulatsydney]

In the example uniswap_v2_usdc_swap, it creates a type as following:
pub type AlloyCacheDB = CacheDB<WrapDatabaseAsync<AlloyDB<Http, Ethereum, RootProvider<Http>>>>;

I want to follow this approach, however I can't find out how to import WrapDatabaseAsync.
In the example it simples use revm::database_interface::WrapDatabaseAsync. However in my code, database_interface doesn't exist in revm.
My REVM version is 19.3.0.

If I check the documentation, I can see that this is a pub struct. https://bluealloy.github.io/revm/docs/revm_database_interface/async_db/struct.WrapDatabaseAsync.html

Appreciate if anyone could give a help.

You would need a asyncdb feature enabled
