Struct TapDerivation

pub struct TapDerivation {
    pub leaf_hashes: Vec<TapLeafHash>,
    pub origin: KeyOrigin,
}

A compact size unsigned integer representing the number of leaf hashes, followed by a list of leaf hashes, followed by the 4 byte master key fingerprint concatenated with the derivation path of the public key. The derivation path is represented as 32-bit little endian unsigned integer indexes concatenated with each other. Public keys are those needed to spend this output. The leaf hashes are of the leaves which involve this public key. The internal key does not have leaf hashes, so can be indicated with a hashes len of 0. Finalizers should remove this field after PSBT_IN_FINAL_SCRIPTWITNESS is constructed.

Implementations

impl TapDerivation

pub fn with_internal_pk( xpub_origin: XkeyOrigin, terminal: Terminal, ) -> TapDerivation

Trait Implementations

impl Clone for TapDerivation

fn clone(&self) -> TapDerivation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TapDerivation

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

Formats the value using the given formatter.

impl Decode for TapDerivation

fn decode(reader: &mut impl Read) -> Result<TapDerivation, DecodeError>

fn deserialize(bytes: impl AsRef<[u8]>) -> Result<Self, PsbtError>

impl Encode for TapDerivation

A compact size unsigned integer representing the number of leaf hashes, followed by a list of leaf hashes, followed by the 4 byte master key fingerprint concatenated with the derivation path of the public key. The derivation path is represented as 32-bit little endian unsigned integer indexes concatenated with each other.

fn encode(&self, writer: &mut dyn Write) -> Result<usize, IoError>

impl Hash for TapDerivation

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 PartialEq for TapDerivation

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