Example showing how to deploy a new contract instance about rust-web3 HOT 5 CLOSED

Also, If you can give some hints for how to do it, I'd be happy to write such an example myself.

Hi @casey, deploying a contract is as simple as sending transaction without a recipient.
You need a contract deployment bytecode (obtaining it is outside the scope of this library, you can use solc to do that) and you put it in data field of the transaction.

    let bytecode: Vec<u8> = "cafe123456789".parse().unwrap();
    let tx = web3::types::TransactionRequest {
      from: 5.into(),
      to: None,
      gas: Some(125.into()),
      gas_price: None,
      value: None,
      data: Some(bytecode.into()),
      nonce: None,
      condition: None,
    };
    let hash = web3.eth().send_transaction(tx).wait();

I'm working on creating an example now, which I'll submit for inclusion once it's done.

One question, if the contract constructor takes a value, how is that value passed in the TransactionRequest?

Hey! Seems that indeed it's not yet possible without using ethabi externally.
I'll implement a convenience method to deploy a contract tomorrow - it will handle encoding of constructor parameters and sending a transaction.

Thanks for digging into this!

Sweet, thank you!
