Struct XPub

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

Extended Public Key (Point + ChainCode)

Implementations

impl XPub

pub fn from_bytes(bytes: [u8; 64]) -> Self

create a XPub by taking ownership of the given array

pub fn from_pk_and_chaincode(pk: &[u8; 32], chain_code: &[u8; 32]) -> Self

create a XPub by its components (a 32 bytes public key, and a 32 bytes chain code)

pub fn from_slice(bytes: &[u8]) -> Result<Self, PublicKeyError>

create a XPub from the given slice. This slice must be of size XPUB_SIZE otherwise it will return Option::None.

pub fn verify<T>(&self, message: &[u8], signature: &Signature<T>) -> bool

verify a signature

pub fn derive( &self, scheme: DerivationScheme, index: DerivationIndex, ) -> Result<Self, DerivationError>

pub fn get_without_chaincode(&self, out: &mut [u8; 32])

pub fn public_key_bytes(&self) -> &[u8; 32]

pub fn public_key_slice(&self) -> &[u8]

pub fn chain_code_slice(&self) -> &[u8]

pub fn public_key(&self) -> [u8; 32]

pub fn chain_code(&self) -> &[u8; 32]

Trait Implementations

impl AsRef<[u8]> for XPub

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for XPub

fn clone(&self) -> XPub

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for XPub

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

Formats the value using the given formatter.

impl Display for XPub

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

Formats the value using the given formatter.

impl From<XPub> for [u8; 64]

fn from(v: XPub) -> [u8; 64]

Converts to this type from the input type.

impl Hash for XPub

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 XPub

fn eq(&self, rhs: &XPub) -> 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.
