Struct schnorr::keys::XPublicKey

pub struct XPublicKey {
    pub key: PublicKey,
    // some fields omitted
}

Xpub represents an extended public key.

Fields

key: PublicKey

Methods

impl XPublicKey

pub fn derive_intermediate_key(
    &self,
    customize: impl FnOnce(&mut Transcript)
) -> XPublicKey

Returns a intermediate child pubkey. Users must provide customize, in order to separate sibling keys from one another through unique derivation paths.

pub fn derive_key(&self, customize: impl FnOnce(&mut Transcript)) -> PublicKey

Returns a leaf Xpub, which can safely be shared. Users must provide customize, in order to separate sibling keys from one another through unique derivation paths.

pub fn to_bytes(&self) -> [u8; 64]

Serializes this Xpub to a sequence of bytes.

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Decodes an Xpub from a 64-byte array, and fails if the provided array is not exactly 64 bytes, or if the compressed point fails to decompress.

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for XPublicKey

fn default() -> XPublicKey

Returns the "default value" for a type.
