tonlibjson as data providertonlib-sys - https://github.com/ston-fi/tonlib-sys
You can build the library using the following command:
bash
cargo build
To use this library in your Rust application, add the following to your Cargo.toml file:
toml
[dependencies]
tonlib = "0.5"
Then, in your Rust code, you can import the library with:
rust
use tonlib;
Creating a Cell and writing data to it:
rust
let mut writer = CellBuilder::new();
let addr = TonAddress::from_base64_url("EQDk2VTvn04SUKJrW7rXahzdF8_Qi6utb0wj43InCu9vdjrR")?;
let cell = writer
.store_u32(32, 0xFAD45AADu32)?
.store_bit(true)?
.store_u8(8, 234u8)?
.store_slice(&[0xFA, 0xD4, 0x5A, 0xAD, 0xAA, 0x12, 0xFF, 0x45])?
.store_address(&addr)?
.store_string("Hello, TON")?
.build()?;
Reading data from a Cell:
rust
let mut reader = cell.parser();
let u32_value = reader.load_u32(32)?;
let bit_value = reader.load_bit()?;
let u8_value = reader.load_u8(8)?;
let bytes_value = reader.load_bytes(8)?;
let address_value = reader.load_address()?;
let str_value = reader.load_string(reader.remaining_bytes())?;
To call methods, create a client:
rust
TonClient::set_log_verbosity_level(2); //setup of logging level
let client = TonClientBuilder::new()
.with_pool_size(10)
.with_keystore_dir(String::from("/tmp"))
.build()
.await?;
TonClient::set_log_verbosity_level(2); sets the logging level.
By default, the connection is made to mainnet. But you can also specify a test network when creating the client:
rust
let client = TonClientBuilder::new()
.with_connection_params(&TonConnectionParams {
config: TESTNET_CONFIG.to_string(),
blockchain_name: None,
use_callbacks_for_network: false,
ignore_cache: false,
keystore_dir: None,
})
.with_pool_size(10)
.build()
.await?;
After creating the client, you can call methods on the TON blockchain:
rust
let info: BlocksMasterchainInfo = client.get_masterchain_info().await?;
println!("MasterchainInfo: {:?}", &info);
let block_id = BlockId {
workchain: info.last.workchain,
shard: info.last.shard,
seqno: info.last.seqno,
};
let block_id_ext = client.lookup_block(1, &block_id, 0, 0).await?;
println!("BlockIdExt: {:?}", &block_id_ext);
let block_shards: BlocksShards = client.get_block_shards(&info.last).await?;
let mut shards = block_shards.shards.clone();
println!("Shards: {:?}", &block_shards);
shards.insert(0, info.last.clone());
for shard in &shards {
println!("Processing shard: {:?}", shard);
let workchain = shard.workchain;
let txs: BlocksTransactions = client
.get_block_transactions(&shard, 7, 1024, &NULL_BLOCKS_ACCOUNT_TRANSACTION_ID)
.await?;
println!(
"Number of transactions: {}, incomplete: {}",
txs.transactions.len(),
txs.incomplete
);
for tx_id in txs.transactions {
let mut t: [u8; 32] = [0; 32];
t.clone_from_slice(tx_id.account.as_slice());
let addr = TonAddress::new(workchain, &t);
let id = InternalTransactionId {
hash: tx_id.hash.clone(),
lt: tx_id.lt,
};
let tx = client
.get_raw_transactions_v2(addr.to_hex().as_str(), &id, 1, false)
.await?;
println!("Tx: {:?}", tx.transactions[0])
}
}
You can get the account state for any contract:
rust
let r = client
.get_account_state("EQB3ncyBUTjZUA5EnFKR5_EnOMI9V1tTEAAPaiU71gc4TiUt")
.await;
Methods for working with tokens and wallets:
```rust let mastercontract = TonContract::new( &client, &"EQDk2VTvn04SUKJrW7rXahzdF8Qi6utb0wj43InCu9vdjrR".parse()?, ); let jettondata = mastercontract.getjettondata().await?;
let walletcontract = TonContract::new( &client, &"EQCGY3OVLtD9KRcOsP2ldQDtuY0FMzV7wPoxjrFbayBXc23c".parse()?, ); let walletdata = walletcontract.getwallet_data().await?; ```
To load the metadata of the token, there is JettonContentLoader:
rust
let loader = JettonContentLoader::default()?;
let content_res = loader.load(&jetton_data.content).await?;
Get the wallet address for the token:
rust
let contract = TonContract::new(
&client,
&"EQDk2VTvn04SUKJrW7rXahzdF8_Qi6utb0wj43InCu9vdjrR".parse()?,
);
let owner_address = TonAddress::from_base64_url(
"EQB2BtXDXaQuIcMYW7JEWhHmwHfPPwa-eoCdefiAxOhU3pQg",
)?;
let wallet_address = contract.get_wallet_address(&owner_address).await?;
Create key pair from secret phrase (mnemonic)
rust
let mnemonic_str = "<your secret phrase composed of 24 words>"
let mnemonic: Mnemonic = Mnemonic::from_str(mnemonic_str, &None).unwrap();
let key_pair: KeyPair = mnemonic.to_key_pair().unwrap();
And now you are ready to send transfer messages to TON blockchain.
Create a jetton transfer:
```rust
const SELFADDR: TonAddress = "
let client = TonClient::default().await?; let jettonmaster = TonContract::new(&client, &JETTONMASTERADDR); let selfjettonwalletaddr = jettonmaster.getwalletaddress(&SELFADDR).await?;
let wallet = TonWallet::derive(0, WalletVersion::V4R2, &keypair)?;
let dest: TonAddress = "
let hash = client.sendrawmessagereturnhash(tx.as_slice()).await?; ```
Create a simple transfer:
rust
let client = TonClient::default().await?;
let wallet = TonWallet::derive(0, WalletVersion::V4R2, &key_pair)?;
let dest: TonAddress = "<destination wallet address>".parse()?;
let value = BigUint::from(10000000u64); // 0.01 TON
let transfer = TransferBuilder::new(&dest, &value).build()?;
let now = SystemTime::now()
.duration_since(SystemTime::UNIX_EPOCH)?
.as_secs()? as u32;
let body = wallet.create_external_body(now + 60, SEQNO, transfer)?;
let signed = wallet.sign_external_body(&body)?;
let wrapped = wallet.wrap_signed_body(signed)?;
let boc = BagOfCells::from_root(wrapped);
let tx = boc.serialize(true)?
let hash = client.send_raw_message_return_hash(tx.as_slice()).await?;
