Hi guys, I’m trying to create uid based on Address and AssetId in the indexer lib file, it works well like uid(event.address) and uid(event.asset_id.0) but how to make it together?
I’m trying to store data like this:
storage {
user_collateral: StorageMap<(Address, AssetId), u64> = StorageMap {},
}

The uid function expects a contiguous slice of bytes.
The following is not a valid way to join two separate byte arrays together in rust, as it just creates a slice of two nested slices:
[..event.address, ..event.asset_id.0]
To create a flattened byte slice from two separate slices you’ll need to concat them.

Oh, sorry, stupid question, that works for me
