Struct coins_bip32::derived::DerivedPubkey

pub struct DerivedPubkey { /* private fields */ }

A Pubkey with its derivation. Primarily used by PSBT.

Implementations

impl DerivedPubkey

pub fn to_sec1_bytes(&self) -> [u8; 33]

Get the compressed sec1 representation of the public key.

impl DerivedPubkey

pub const fn new(key: VerifyingKey, derivation: KeyDerivation) -> Self

Instantiate a new DerivedPubkey

pub fn pubkey_hash160(&self) -> Hash160Digest

Return the hash of the compressed (Sec1) pubkey.

pub fn fingerprint(&self) -> KeyFingerprint

The fingerprint is the first 4 bytes of the HASH160 of the serialized public key.

Trait Implementations

impl AsRef<VerifyingKey<Secp256k1>> for DerivedPubkey

fn as_ref(&self) -> &VerifyingKey

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

impl Debug for DerivedPubkey

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

Formats the value using the given formatter.

impl DerivedKey for DerivedPubkey

fn derivation(&self) -> &KeyDerivation

Return this key’s derivation

fn same_root<K: DerivedKey>(&self, other: &K) -> bool

true if the keys share a root fingerprint, false otherwise. Note that on key fingerprints, which may collide accidentally, or be intentionally collided.

fn is_possible_ancestor_of<K: DerivedKey>(&self, other: &K) -> bool

true if this key is a possible ancestor of the argument, false otherwise.

fn path_to_descendant<K: DerivedKey>(&self, other: &K) -> Option<DerivationPath>

Returns the path to the descendant, or None if the argument is definitely not a descendant.

impl<D> DigestVerifier<D, Signature<Secp256k1>> for DerivedPubkey

where D: Digest + FixedOutput<OutputSize = U32>,

fn verify_digest(&self, digest: D, signature: &Signature) -> Result<(), Error>

Verify the signature against the given Digest output.
