Let's say I want to write a little rust CLI that just stores like "notes to self" as nostr notes with some random kind, and saves them to my relays. What crates should I use? enostr? Fine with forking it if some small things need changing? Or https://github.com/rust-nostr/nostr/tree/master/crates/nostr-sdk with `ndb` feature (cc @Yuki Kishimoto )? Want to make a nostr thing this week and would like to try out nostrdb while I'm at it ...
