Expand description
Transaction represents an individual, serializable Themelio transaction.
Fields
kind: TxKind
inputs: Vec<CoinID>
outputs: Vec<CoinData>
fee: CoinValue
scripts: Vec<Covenant>
data: Vec<u8>
sigs: Vec<HexBytes>
Implementations
An empty transaction with kind Normal, no inputs, no fees, etc.
Creates a new transaction with the given kind, no inputs, no outputs, no nothing.
Replaces the inputs of the transaction
Replaces the outputs of the transaction
Add an output
Replaces the scripts of the transaction
Add a script to the transaction
Checks whether or not the transaction is well formed, respecting coin size bounds and such. Does not fully validate the transaction.
hash_nosigs returns the hash of the transaction with a zeroed-out signature field. This is what signatures are computed against.
sign_ed25519 consumes the transaction, appends an ed25519 signature, and returns it.
total_outputs returns a HashMap mapping each type of coin to its total value. Fees will be included in the Mel cointype.
scripts_as_map returns a HashMap mapping the hash of each script in the transaction to the script itself.
Returns the minimum fee of the transaction at a given fee multiplier, with a given “ballast”.
Convenience function that constructs a CoinID that points to a certain output of this transaction. Panics if the index is out of bounds.
pub fn applied_fee(
self,
fee_multiplier: u128,
ballast: u128,
deduct_from_idx: usize
) -> Option<Self>
👎 Deprecated
pub fn applied_fee(
self,
fee_multiplier: u128,
ballast: u128,
deduct_from_idx: usize
) -> Option<Self>
Convenience function that applies the correct fee. Call this before signing the transaction, with a ballast that’s an upper bound on the number of bytes added to the transaction as signatures. 100 is a good value for a ballast. Provide the index of the output to deduct from; returns None if the output doesn’t have enough money to cover fees.
Deprecated: you should use TransactionBuilder instead.
