You can see the REQs using the debug log level

nostr:nprofile1qqsprwdgjszdhucrfelp3p46nhzvd5mk7gu6zxp8r0fwc4n63zv9pnsppemhxue69uhkummn9ekx7mp0rqtknc, yeah, you can use nostrdb APIs directly for the zero-copy queries and nostr-sdk for the networking stuff.

You can eventually clone the nostrdb instance and pass it to nostr-sdk just to automatically save the events received from the relays into nostrdb.

## rust-nostr v0.40 is out! 🦀

### Summary

Add NIP-38 and NIP-62 support, add nostr parser, to easily parse any text and extract nostr URIs, URLs and more, extend `Tags` capabilities (i.e., add deduplication support), add admission policy, to selectively select which events to allow receiving and which to reject, add Mac Catalyst support for Swift package, many cleanups, refactoring and performance improvements and more!

Happy Birthday!

You have to build manually the event:

```python

encrypted_content = nip04_encrypt(sk, pk, msg)

builder = EventBuilder(4, encrypted_content).tag(Tag.public_key(pk))

client.send_event_builder(builder)

```

I've started working on it here: https://github.com/rust-nostr/nostr/pull/797

For now I've only implemented the algorithm for NIP117. Soon I'll add also support for persistent session state and integration with the nostr-sdk library.

I'll check it soon!

For devs who use rust-nostr bindings and care about app size: use v0.39 or later, older versions are bloated due to a bug in uniffi.

#rustnostr #rust-nostr #kotlin #python #swift #jvm

I've uses both the book and rustlings: https://github.com/rust-lang/rustlings/

There is also the "Rust by example" book: https://doc.rust-lang.org/rust-by-example/

While you read the book, try to make projects from scratch (not just simple ones). At the end, writing code is the best way to learn it.

Yes, it's most likely due to the python version. What python version are you using?

```python

from nostr_sdk import EncryptedSecretKey

encrypted = EncryptedSecretKey.from_bech32("ncryptsec...")

secret_key = encrypted.to_secret_key("")

```

I have never been very active in discussions but working on rust-nostr (at the time called nostr-rs-sdk) since September 2022 🦀

If I remember correctly there were also nostr:nprofile1qqsqfyvdlsmvj0nakmxq6c8n0c2j9uwrddjd8a95ynzn9479jhlth3gpvemhxue69uhkv6tvw3jhytnwdaehgu3wwa5kuef0dec82c33w94xwcmdd3cxketedsux6ertwecrgues0pk8xdrew33h27pkd4unvvpkw3nkv7pe0p68gat58ycrw6ps0fenwdnvva48w0mzwfhkzerrv9ehg0t5wf6k2qgnwaehxw309ac82unsd3jhqct89ejhxtcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsh8njvk and nostr:nprofile1qqswuyd9ml6qcxd92h6pleptfrcqucvvjy39vg4wx7mv9wm8kakyujgpypmhxue69uhkx6r0wf6hxtndd94k2erfd3nk2u3wvdhk6w35xs6z7qgwwaehxw309ahx7uewd3hkctcpypmhxue69uhkummnw3ezuetfde6kuer6wasku7nfvuh8xurpvdjj7a0nq40

I usually copy the stuff I already exposed in the UniFFI bindings and adapt it to the flutter_rust_bridge.

So, in the case of metadata stuff, I would copy and adapt this: https://github.com/rust-nostr/nostr/blob/d7a8372e28a5dd7e1ce02b725ee0b43c798e332f/bindings/nostr-sdk-ffi/src/protocol/nips/nip01.rs

To adapt it, I follow these docs https://cjycode.com/flutter_rust_bridge/ or I just check the other modules I already adapted. In short: replace the uniffi macros with `frb` and use the `Result` from anyhow. If a new module is added, it must be exported in the `lib/nostr_sdk.dart` file.

Done, I've exposed the NostrDatabase, added some other Client method and released the v0.39 (tagged in the git repo, I can't publish it to pub.dev).

Nice, so I'll expose the database soon

The rust library for flutter compiles to wasm but I don't know how to pack and ship the flutter package for web. For the desktop and mobile platforms I use cargokit but it doesn't work for the web.

For now are available: Keys signer (with both NIP04 and NIP44 support), NIP59, event de/serialization, event building and the SDK Client (NIP42 auto authentication, gossip, event sending, event fetching and subscriptions).

I'll add the other stuff as I find the time. If you need something specific, let me know that I'll expose it.

Nice! Yeah haha

## rust-nostr v0.39 is out! 🦀

### Summary

Add NIP96 support, add NIP22 helpers, NIP01 adjustments, add `try_connect` and `wait_for_connection` methods for better connection handling, support for custom WebSocket clients (both in Rust, Python, Kotlin and Swift), new JVM bindings (Linux, macOS and Windows), huge reduction of UniFFI bindings binaries size, many cleanups, refactoring and performance improvements and more!
