NostrO2

This crate is our first approach at building simple Rust tools for interacting with the Nostr ecosystem.

Features

• User Key Creation: Generate user keys with ease.
• Object Handling: Create and sign objects to ensure data integrity.
• Relay Connectivity: Connect to Nostr relays to send and receive messages seamlessly.
• Nostr Types: Static typing for Nostr data structures, from Notes to Relay messages.

Installation

Add nostro2 to your Cargo.toml dependencies:

toml [dependencies] nostro2 = "0.1.4"

Example

Using this library is straightforward. Connect to a relay, send a subscription event, and await the received messages.

Rust and serde allow for performant parsing of the notes into objects, which can then be pattern matched with ease.

```rust let nostr_relay = NostrRelay::new("wss://nostr.bongbong.com").await;

let filter: Value = json!({ "authors": vec!(pubkey), "kinds": [1] });

nostr_relay.subscribe(filter).await;

while let Some(Ok(result)) = nostrrelay.readfromrelay().await { match result { RelayNotice::EVENT(notice, id, note) => { info!("SignedNote: {:?}", note.getcontent()); } _ => { nostrrelay.close().await.expect("Error"); return Err("Error".tostring()); } } } ```
