Struct hwi::types::HWIExtendedPubKey

pub struct HWIExtendedPubKey {
    pub xpub: Xpub,
}

Fields

xpub: Xpub

Methods from Deref<Target = Xpub>

pub fn derive_pub<C, P>( &self, secp: &Secp256k1<C>, path: &P ) -> Result<Xpub, Error>

where C: Verification, P: AsRef<[ChildNumber]>,

Attempts to derive an extended public key from a path.

The path argument can be any type implementing AsRef<ChildNumber>, such as DerivationPath, for instance.

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<Xpub, 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) -> XKeyIdentifier

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.

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 = Xpub

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 for HWIExtendedPubKey

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

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

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.
