Describe the bug

When indexing non-primitive, custom types in a log event, is the rust binding that is generated in the topic the abi encoded hash for the custom type? I'm looking at the Initialize log in the v4 contracts. The indexed Currency type is an address but the rust binding is declaring it a FixedBytes<32>.

I am generating the bindings using foundry with the v4 contracts as git submodule working on rev e74c9bbd42fe0fb1c20e2560e72d5c2e62fb45f1.

event Initialize(PoolId indexed id, Currency indexed currency0, Currency indexed currency1, uint24 fee, int24 tickSpacing, address hooks, uint160 sqrtPriceX96, int24 tick);
