Struct Extractor 

pub struct Extractor(/* private fields */);

Implements the BIP-370 Finalized role.

Implementations

impl Extractor

pub fn new(psbt: Psbt) -> Result<Self, ExtractError>

Creates an Extractor.

An extractor can only accept a PSBT that has been finalized.

pub fn id(&self) -> Txid

Returns this PSBT’s unique identification.

impl Extractor

pub const DEFAULT_MAX_FEE_RATE: FeeRate

The default max_fee_rate value used for extracting transactions with Self::extract_tx.

As of 2023, even the biggest overpayers during the highest fee markets only paid around 1000 sats/vByte. 25k sats/vByte is obviously a mistake at this point.

pub fn extract_tx(&self) -> Result<Transaction, ExtractTxFeeRateError>

An alias for Self::extract_tx_fee_rate_limit.

pub fn extract_tx_fee_rate_limit( &self, ) -> Result<Transaction, ExtractTxFeeRateError>

Extracts the Transaction from a Psbt by filling in the available signature information.

Errors

ExtractTxError variants will contain either the Psbt itself or the Transaction that was extracted. These can be extracted from the Errors in order to recover. See the error documentation for info on the variants. In general, it covers large fees.

pub fn extract_tx_with_fee_rate_limit( &self, max_fee_rate: FeeRate, ) -> Result<Transaction, ExtractTxFeeRateError>

Extracts the Transaction from a Psbt by filling in the available signature information.

pub fn extract_tx_unchecked_fee_rate( &self, ) -> Result<Transaction, ExtractTxError>

Perform Self::extract_tx_fee_rate_limit without the fee rate check.

This can result in a transaction with absurdly high fees. Use with caution.

Trait Implementations

impl Clone for Extractor

fn clone(&self) -> Extractor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Extractor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Extractor

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Extractor

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 PartialEq for Extractor

fn eq(&self, other: &Extractor) -> 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 Serialize for Extractor

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
