Struct TxOut

pub struct TxOut {
    pub value: u64,
    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: u64

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 fn weight(&self) -> usize

The weight of the txout in witness units

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.

pub fn minimal_non_dust(script_pubkey: ScriptBuf) -> TxOut

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 duplicate 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<(), Error>

Formats the value using the given formatter.

impl Decodable for TxOut

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

where R: Read + ?Sized,

Decode Self from a size-limited reader.

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

where R: Read + ?Sized,

Decode an object with a well-defined format.

impl Default for TxOut

fn default() -> TxOut

Returns the “default value” for a type.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for TxOut

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

where R: Write + ?Sized,

Encodes an object with a well-defined format.

impl Hash for TxOut

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

where __H: Hasher,

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) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TxOut

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd 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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Readable for TxOut

fn read<R>(r: &mut R) -> Result<TxOut, DecodeError>

where R: Read,

Reads a Self in from the given Read.

impl Serialize for TxOut

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Writeable for TxOut

fn write<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Writer,

Writes self out to the given Writer.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
