Struct miniscript::descriptor::DefiniteDescriptorKey

pub struct DefiniteDescriptorKey(/* private fields */);

A DescriptorPublicKey without any wildcards.

Implementations

impl DefiniteDescriptorKey

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

Computes the public key corresponding to this descriptor key. When deriving from an XOnlyPublicKey, it adds the default 0x02 y-coordinate and returns the obtained full bitcoin::PublicKey. All BIP32 derivations always return a compressed key

Will return an error if the descriptor key has any hardened derivation steps in its path. To avoid this error you should replace any such public keys first with translate_pk.

pub fn master_fingerprint(&self) -> Fingerprint

The fingerprint of the master key associated with this key, 0x00000000 if none.

pub fn full_derivation_path(&self) -> Option<DerivationPath>

Full path from the master key if not a multipath extended key.

pub fn full_derivation_paths(&self) -> Vec<DerivationPath>

Full paths from the master key. The vector will contain just one path for single keys, and multiple ones for multipath extended keys

pub fn as_descriptor_public_key(&self) -> &DescriptorPublicKey

Reference to the underlying DescriptorPublicKey

pub fn into_descriptor_public_key(self) -> DescriptorPublicKey

Converts the definite key into a generic one
