Enum miniscript::DescriptorPublicKey

pub enum DescriptorPublicKey {
    SinglePub(DescriptorSinglePub),
    XPub(DescriptorXKey<ExtendedPubKey>),
}

The MiniscriptKey corresponding to Descriptors. This can either be Single public key or a Xpub

Variants

SinglePub(DescriptorSinglePub)

Single Public Key

XPub(DescriptorXKey<ExtendedPubKey>)

Xpub

Implementations

impl DescriptorPublicKey

pub fn master_fingerprint(&self) -> Fingerprint

The fingerprint of the master key associated with this key

pub fn full_derivation_path(&self) -> DerivationPath

Full path, from the master key

For wildcard keys this will return the path up to the wildcard, so you can get full paths by appending one additional derivation step, according to the wildcard type (hardened or normal)

pub fn is_deriveable(&self) -> bool

Whether or not the key has a wildcards

pub fn derive(mut self: Self, index: u32) -> DescriptorPublicKey

If this public key has a wildcard, replace it by the given index

Panics if given an index ≥ 2^31

pub fn derive_public_key<C: Verification>(
    &self,
    secp: &Secp256k1<C>
) -> Result<PublicKey, ConversionError>

Computes the public key corresponding to this descriptor key

Will return an error if the descriptor key has any hardened derivation steps in its path, or if the key has any wildcards.

To ensure there are no wildcards, call .derive(0) or similar; to avoid hardened derivation steps, start from a DescriptorSecretKey and call as_public, or call TranslatePk2::translate_pk2 with some function which has access to secret key data.

Trait Implementations

impl Clone for DescriptorPublicKey

fn clone(&self) -> DescriptorPublicKey

Returns a copy of the value.

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

Formats the value using the given formatter.

impl Eq for DescriptorPublicKey

impl FromStr for DescriptorPublicKey

type Err = DescriptorKeyParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>
