Implementations

impl XpubkeyCore

pub fn identifier(&self) -> XpubIdentifier

Computes XpubIdentifier of the key

Computes Fingerprint of the key

impl XpubkeyCore

pub fn derive( self, secp: &Secp256k1<VerifyOnly>, terminal: impl IntoIterator<Item = UnhardenedIndex>, ) -> PublicKey

Derives public key for a given terminal path

Trait Implementations

impl Clone for XpubkeyCore

fn clone(&self) -> XpubkeyCore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for XpubkeyCore

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

Formats the value using the given formatter.

impl Display for XpubkeyCore

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

Formats the value using the given formatter.

impl From<ExtendedPubKey> for XpubkeyCore

fn from(xpub: ExtendedPubKey) -> Self

Converts to this type from the input type.

impl Hash for XpubkeyCore

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 XpubkeyCore

fn cmp(&self, other: &XpubkeyCore) -> 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 XpubkeyCore

fn eq(&self, other: &XpubkeyCore) -> 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 XpubkeyCore

fn partial_cmp(&self, other: &XpubkeyCore) -> 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 StrictDecode for XpubkeyCore

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

Decode with the given std::io::Read instance; must either construct an instance or return implementation-specific error type.

fn strict_deserialize(data: impl AsRef<[u8]>) -> Result<Self, Error>

Tries to deserialize byte array into the current type using StrictDecode::strict_decode. If there are some data remains in the buffer once deserialization is completed, fails with Error::DataNotEntirelyConsumed. Use io::Cursor over the buffer and StrictDecode::strict_decode to avoid such failures.

fn strict_file_load(path: impl AsRef<Path>) -> Result<Self, Error>

Reads data from file at path and reconstructs object from it. Fails with Error::DataNotEntirelyConsumed if file contains remaining data after the object reconstruction.

impl StrictEncode for XpubkeyCore

fn strict_encode<E: Write>(&self, e: E) -> Result<usize, Error>

Encode with the given std::io::Write instance; must return result with either amount of bytes encoded – or implementation-specific error type.

fn strict_serialize(&self) -> Result<Vec<u8>, Error>

Serializes data as a byte array using StrictEncode::strict_encode function

fn strict_file_save(&self, path: impl AsRef<Path>) -> Result<usize, Error>

Saves data to a file at a given path. If the file does not exists, attempts to create the file. If the file already exists, it gets truncated.
