Struct bitcoin::blockdata::transaction::TxOut

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

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

impl TxOut

pub const NULL: Self = _

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

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.

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.

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.

Trait Implementations

impl Clone for TxOut

fn clone(&self) -> TxOut

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TxOut

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

Formats the value using the given formatter.

impl Decodable for TxOut

fn consensus_decode_from_finite_reader<R: Read + ?Sized>( r: &mut R ) -> Result<TxOut, Error>

Decode Self from a size-limited reader.

fn consensus_decode<R: Read + ?Sized>(r: &mut R) -> Result<TxOut, Error>

Decode an object with a well-defined format.

impl<'de> Deserialize<'de> for TxOut

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for TxOut

fn consensus_encode<R: Write + ?Sized>(&self, r: &mut R) -> Result<usize, Error>

Encodes an object with a well-defined format.

impl Hash for TxOut

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TxOut

fn cmp(&self, other: &TxOut) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<TxOut> for TxOut

fn eq(&self, other: &TxOut) -> 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.

impl PartialOrd<TxOut> for TxOut

fn partial_cmp(&self, other: &TxOut) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TxOut

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
