Solana Rust Client Extension

This crate provides extensions for the Solana Rust client, focusing on compute unit estimation and optimization. It also provides transaction execution details via the ReturnStruct for more robust transaction processing.

Features

• Estimates compute units for Solana transactions
• Optimizes compute unit usage by adding a compute budget instruction
• Returns detailed transaction execution information:
  • Success/failure status
  • Compute units used
  • Detailed result message or error information

Usage

To use this crate, add it to your Cargo.toml file:

[dependencies]
solana-client-ext = { git = "https://github.com/bergabman/Solana-Rust-Client-Extension.git", version ="0.1.0"} # Replace with the right version

Basic Usage Example

use solana_client::rpc_client::RpcClient;
use solana_client_ext::RpcClientExt;
use solana_sdk::{
    message::Message, signature::Keypair, signer::Signer, system_instruction,
    transaction::Transaction,
};

fn main() {
    let rpc_client = RpcClient::new("https://api.devnet.solana.com");
    let keypair = Keypair::new();
    let keypair2 = Keypair::new();
    let created_ix = system_instruction::transfer(&keypair.pubkey(), &keypair2.pubkey(), 10000);
    let mut msg = Message::new(&[created_ix], Some(&keypair.pubkey()));

    let optimized_cu = rpc_client
        .optimize_compute_units_msg(&mut msg, &[&keypair])
        .unwrap();
    println!("Optimized compute units: {}", optimized_cu);

    let tx = Transaction::new(&[&keypair], msg, rpc_client.get_latest_blockhash().unwrap());
    let result = rpc_client
        .send_and_confirm_transaction_with_spinner(&tx)
        .unwrap();

    println!(
        "Transaction signature: https://explorer.solana.com/tx/{}?cluster=devnet",
        result
    );
}

Using ReturnStruct for Detailed Transaction Information

You can also get detailed transaction results using the ReturnStruct:

use solana_client::rpc_client::RpcClient;
use solana_client_ext::{RpcClientExt, RollUpChannel};
use solana_sdk::{
    pubkey::Pubkey, signature::Keypair, signer::Signer, system_instruction,
    transaction::Transaction,
};

fn main() {
    let rpc_client = RpcClient::new("https://api.devnet.solana.com");
    let keypair = Keypair::new();
    
    // Create a simple transfer transaction
    let transfer_ix = system_instruction::transfer(
        &keypair.pubkey(), 
        &Pubkey::new_unique(), 
        10000
    );
    let msg = Message::new(&[transfer_ix], Some(&keypair.pubkey()));
    let blockhash = rpc_client.get_latest_blockhash().unwrap();
    let tx = Transaction::new(&[&keypair], msg, blockhash);
    
    // Process the transaction and get detailed results
    let accounts = tx.message.account_keys.clone();
    let rollup_c = RollUpChannel::new(accounts, &rpc_client);
    let results = rollup_c.process_rollup_transfers(&[tx.clone()]);
    
    // Display transaction results
    for (i, result) in results.iter().enumerate() {
        println!("Transaction {}: Success={}, CU={}, Result: {}", 
            i, result.success, result.cu, result.result);
    }
}
