Solana TPU client and sending versioned transactions

Question

The solana tpu client (rust) takes a &Transaction argument however I deal with VersionedTransaction's.

I would like to know 2 things..

1. How can I send a VersionedTransaction via the tpu client.
2. How can I serialize a VersionedTransaction into base64.

I create the transactions using the solana_sdk like so

let message = V0Message::try_compile(
    &wallet.pubkey(),
    &instructions,
    &[],
    block_hash
).unwrap();

let versioned_message = VersionedMessage::V0(message);
let transaction = VersionedTransaction::try_new(versioned_message, &[wallet]).unwrap();

Answer 1

This should probably get fixed at the TPU client level, but in the meantime, you can serialize the versioned transaction and use send_wire_transaction, ie:

tpu_client.send_wire_transaction(bincode::serialize(&transaction).unwrap())
