Solana Transaction Crawler

Minimum Example

```rust use anyhow::Result; use solanaclient::rpcclient::RpcClient; use solanatransactioncrawler::{ crawler::{Crawler, IxAccount}, filters::{IxNumberAccounts, SuccessfulTxFilter, TxHasProgramId}, }; use solana_program::pubkey;

[tokio::main]

async fn main() -> Result<()> { // Set up Solana RPC client. let client = RpcClient::new("https://rpc.ankr.com/solana");

// The pubkey of the account you want to crawl for transactions. In this example we use the DeGods CMV1 pubkey.
let candy_machine_id = pubkey!("9MynErYQ5Qi6obp4YwwdoDmXkZ1hYVtPUqYmJJ3rZ9Kn");

// Create the Crawler object.
let mut crawler = Crawler::new(client, candy_machine_id);

// Define filters.

// We only want to crawl transactions that have the program id of the Candy Machine V1 program.
let has_program_id = TxHasProgramId::new("cndyAnrLdpjq1Ssp1z8xxDsB8dxe7u4HL5Nxi2K5WXZ");

// This filter gives us only successful transactions, filtering out any with errors.
let successful_tx = SuccessfulTxFilter;

// We know the mintNFT instruction has exactly 14 accounts and is the only instruction on that program with that number of accounts.
let ix_num_accounts = IxNumberAccounts::EqualTo(14);

// Specify accounts we want to retrieve from the transaction.
// 'Unparsed' means we have to specify the actual index of the account in the instruction.
// The mint account is the sixth account in the instruction.
let mint_account = IxAccount::unparsed("mint", 5);

// Add filters to Crawler
crawler
    .add_tx_filter(has_program_id)
    .add_tx_filter(successful_tx)
    .add_ix_filter(ix_num_accounts)
    .add_account_index(mint_account);

// Run the Crawler.
let crawled_accounts = crawler.run().await?;

// We labeled our account "mint" so we look it up by the label.
let mint_addresses = &crawled_accounts["mint"];
println!("Items found: {:?}", mint_addresses.len());

Ok(())

} ```
