Struct bpstd::UnsignedTx

pub struct UnsignedTx {
    pub version: TxVer,
    pub inputs: Confined<Vec<UnsignedTxIn>, 0, bc::::coding::VarIntArray::{constant#1}>,
    pub outputs: Confined<Vec<TxOut>, 0, bc::::coding::VarIntArray::{constant#1}>,
    pub lock_time: LockTime,
}

Structure representing data on unsigned transaction the way it is stored in PSBTv1 global key.

We can’t use Tx since PSBT may contain unsigned transaction with zero inputs, according to BIP-174 test cases. Tx containing zero inputs is an invalid structure, prohibited by consensus. An attempt to deserialize it will be incorrectly identified as a Segwit transaction (since zero inputs is the trick which was used to make Segwit softfork) and fail with invalid segwit flag error (since the second byte after 0 segwit indicator must be 01 and not a number of inputs) fail to parse outputs (for transactions containing just a one output).

UnsignedTx also ensures invariant that none of its inputs contain witnesses or sigscripts.

Performs copy-assignment from source.

impl Debug for UnsignedTx

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Decode for UnsignedTx

fn deserialize(bytes: impl AsRef<[u8]>) -> Result<Self, PsbtError>

impl Encode for UnsignedTx

fn encode(&self, writer: &mut dyn Write) -> Result<usize, IoError>

impl From<Tx> for UnsignedTx

fn from(tx: Tx) -> UnsignedTx

Converts to this type from the input type.

impl From<UnsignedTx> for Tx

Converts to this type from the input type.

impl Hash for UnsignedTx

fn hash<__H>(&self, state: &mut __H)

impl PartialEq for UnsignedTx

fn eq(&self, other: &UnsignedTx) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
