)

Append a new unsigned input to the transaction.

When the transaction is constructed, Transaction::sign_inputs should be called for every secret key used with this method.

The production of the signatures can be done only after the full transaction skeleton is built because the input of the hash message is the ID of the final transaction.

pub fn sign_inputs(&mut self, secret: &SecretKey)

For all inputs of type coin, check if its owner equals the public counterpart of the provided key. Sign all matches.

pub fn metered_bytes_size(&self) -> usize

Used for accounting purposes when charging byte based fees
