Struct hwi::types::HWIExtendedPubKey

pub struct HWIExtendedPubKey {
    pub xpub: ExtendedPubKey,
}

Fields

xpub: ExtendedPubKey

Methods from Deref<Target = ExtendedPubKey>

pub fn derive_pub<C, P>(
    &self,
    secp: &Secp256k1<C>,
    path: &P
) -> Result<ExtendedPubKey, Error>where
    C: Verification,
    P: AsRef<[ChildNumber]>,

Attempts to derive an extended public key from a path.

The path argument can be both of type DerivationPath or Vec<ChildNumber>.

pub fn ckd_pub_tweak(
    &self,
    i: ChildNumber
) -> Result<(SecretKey, ChainCode), Error>

Compute the scalar tweak added to this key to get a child key

pub fn ckd_pub<C>(
    &self,
    secp: &Secp256k1<C>,
    i: ChildNumber
) -> Result<ExtendedPubKey, Error>where
    C: Verification,

Public->Public child key derivation

pub fn encode(&self) -> [u8; 78]

Extended public key binary encoding according to BIP 32

pub fn identifier(&self) -> XpubIdentifier

Returns the HASH160 of the chaincode

pub fn fingerprint(&self) -> Fingerprint

Returns the first four bytes of the identifier

Trait Implementations

impl Clone for HWIExtendedPubKey

fn clone(&self) -> HWIExtendedPubKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HWIExtendedPubKey

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

Formats the value using the given formatter.

impl Deref for HWIExtendedPubKey

type Target = ExtendedPubKey

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for HWIExtendedPubKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<HWIExtendedPubKey> for HWIExtendedPubKey

fn eq(&self, other: &HWIExtendedPubKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
