pub struct TxOut {
    pub value: Amount,
    pub script_pubkey: ScriptBuf,
}
Expand description

Bitcoin transaction output.

Defines new coins to be created as a result of the transaction, along with spending conditions (“script”, aka “output script”), which an input spending it must satisfy.

An output that is not yet spent by an input is called Unspent Transaction Output (“UTXO”).

Fields§

§value: Amount

The value of the output, in satoshis.

§script_pubkey: ScriptBuf

The script which must be satisfied for the output to be spent.

Implementations§

source§

impl TxOut

source

pub const NULL: Self = _

This is used as a “null txout” in consensus signing code.

source

pub fn weight(&self) -> Weight

The weight of this output.

Keep in mind that when adding a TxOut to a Transaction the total weight of the transaction might increase more than TxOut::weight. This happens when the new output added causes the output length VarInt to increase its encoding length.

Panics

If output size * 4 overflows, this should never happen under normal conditions. Use Weght::from_vb_checked(self.size() as u64) if you are concerned.

source

pub fn size(&self) -> usize

Returns the total number of bytes that this output contributes to a transaction.

There is no difference between base size vs total size for outputs.

source

pub fn minimal_non_dust(script_pubkey: ScriptBuf) -> Self

Creates a TxOut with given script and the smallest possible value that is not dust per current Core policy.

The current dust fee rate is 3 sat/vB.
