ARRS

Introduction

ARRS is a Rust API implementation of the Arweave client. It can be used to write command line, desktop, or web programs in Rust to use most features of Arweave, including creating, importing, and exporting wallets, checking balance, sending transactions, uploading files, etc..

Arweave is a permanent storage network based on P2P and crypto. For more information, please visit: https://arweave.org/

Example

This program needs OpenSSL. It will download the newest official release of the OpenSSL, and automatically compiles it. Therefore your system needs to have a C compiler, Perl (and perl-core), and make installed.

Then you need to add tokio and arrs into your Cargo.toml:

[dependencies]
arrs = {path = "../arrs"}
tokio = { version = "1.35.1", features = ["full"] }

Print Wallet Address and AR Balance:

use arrs::wallet::ArWallet;
use tokio;

#[tokio::main]
async fn main() {
    let arwallet = ArWallet::new();
    let balance = arwallet.balance();
    let address = arwallet.address();
    println!("Your Arweave Wallet Address is: ");
    println!("{}", address);
    println!("Your AR balance is {}: ", balance.await.unwrap());
}

Import a JSON Web Key (JWK)

use arrs::wallet::ArWallet;
use tokio;
use std::fs::read_to_string;

#[tokio::main]
async fn main() {
    let jwk = read_to_string("./test.json").unwrap();
    let arwallet = ArWallet::from_jwk(&jwk);
    let balance = arwallet.balance();
    let address = arwallet.address();
    println!("Your Arweave Wallet Address is: ");
    println!("{}", address);
    println!("Your AR balance is {}: ", balance.await.unwrap());
}

Create a data transaction; add tags; sign; verify; submit; upload file

use arrs::wallet::ArWallet;
use arrs::uploader::Uploader;
use tokio;
use std::{
    fs::{File, read_to_string},
    io::Read
};

#[tokio::main]
async fn main() {
    let jwk = read_to_string("./test.json").unwrap();
    let ar = ArWallet::from_jwk(&jwk);
    let mut data_file = File::open("./test_image.jpg").unwrap();
    let mut raw_data = Vec::new();
    data_file.read_to_end(&mut raw_data).unwrap();   
    let mut tx = ar.create_data_transaction(&raw_data).await;
    tx.add_tag("Content-Type", "image/jpg");
    tx.add_tag("Test Name 2", "Test Value 2");
    tx.sign();
    match tx.verify() {
        Ok(ok) => println!("{}", ok),
        Err(e) => println!("{:?}", e),
    }
    println!("{:?}", tx.submit().await);
    let mut uploader = Uploader::new(&raw_data);
    while uploader.current_idx() < uploader.chunk_size() {
        println!("{}", uploader.upload(&ar, &raw_data).await.unwrap());
    }
}
