A key-value map for an input of the corresponding index in the unsigned transaction.

Fields

non_witness_utxo: Option<Transaction>

The non-witness transaction this input spends from. Should only be std::option::Option::Some for inputs which spend non-segwit outputs or if it is unknown whether an input spends a segwit output.

witness_utxo: Option<TxOut>

The transaction output this input spends from. Should only be std::option::Option::Some for inputs which spend segwit outputs, including P2SH embedded ones.

partial_sigs: BTreeMap<PublicKey, Vec<u8>>

A map from public keys to their corresponding signature as would be pushed to the stack from a scriptSig or witness.

sighash_type: Option<SigHashType>

The sighash type to be used for this input. Signatures for this input must use the sighash type.

redeem_script: Option<Script>

The redeem script for this input.

witness_script: Option<Script>

The witness script for this input.

bip32_derivation: BTreeMap<PublicKey, KeySource>

A map from public keys needed to sign this input to their corresponding master key fingerprints and derivation paths.

final_script_sig: Option<Script>

The finalized, fully-constructed scriptSig with signatures and any other scripts necessary for this input to pass validation.

final_script_witness: Option<Vec<Vec<u8>>>

The finalized, fully-constructed scriptWitness with signatures and any other scripts necessary for this input to pass validation.

ripemd160_preimages: BTreeMap<Hash, Vec<u8>>

TODO: Proof of reserves commitment RIPEMD160 hash to preimage map

sha256_preimages: BTreeMap<Hash, Vec<u8>>

SHA256 hash to preimage map

hash160_preimages: BTreeMap<Hash, Vec<u8>>

HSAH160 hash to preimage map

hash256_preimages: BTreeMap<Hash, Vec<u8>>

HAS256 hash to preimage map

proprietary: BTreeMap<ProprietaryKey, Vec<u8>>

Proprietary key-value pairs for this input.

unknown: BTreeMap<Key, Vec<u8>>

Unknown key-value pairs for this input.

Trait Implementations

impl Clone for Input

fn clone(&self) -> Input

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Input

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

Formats the value using the given formatter.

impl Decodable for Input

fn consensus_decode<D: Read>(d: D) -> Result<Self, Error>

Decode an object with a well-defined format

impl Default for Input

fn default() -> Input

Returns the “default value” for a type.

impl Encodable for Input

fn consensus_encode<S: Write>(&self, s: S) -> Result<usize, Error>

Encode an object with a well-defined format. Returns the number of bytes written on success.

impl Map for Input

fn insert_pair(&mut self, pair: Pair) -> Result<(), Error>

Attempt to insert a key-value pair.

fn get_pairs(&self) -> Result<Vec<Pair>, Error>

Attempt to get all key-value pairs.

fn merge(&mut self, other: Self) -> Result<(), Error>

Attempt to merge with another key-value map of the same type.

impl PartialEq for Input

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