I think you should explore Rust's if let syntax, it will probably result in something more compact (won't change logic, just more ergonomic).

Implemented. Better like that? :)

Using info log level seems a little excessive. I would use debug level, if any.
Ideally, we should promote metrics / counters rather than logs for these high-frequency observations. Not required for this PR, but it might be a nice addition for a follow up.

Indeed those logs are too much.
I've created an issue out of your metrics proposition

First PR to an open source project!
I spent some time to understand the whole project flow. Please keep in mind I am relatively new to Rust.
So the address filter for the UtxoByAddress reducer has been implemented (Issue #14). How to use it is showed in the exemple .toml
The filter is optional.
I've decided to implement the functionality directly into the "send_set_add" instead of implementing it twice separately in the reduce_byron/alonzo_tx.
I went with the "binary_search" as it seems to be good fast option (https://stackoverflow.com/questions/67525751/what-is-the-fastest-way-to-check-if-something-exist-in-a-vector-in-rust).
I hope it helps! That ain't much but consider it as my entry implication to the project. Feedbacks are ofc more than welcome ;)
