pub struct DescriptorXKey<K> where
    K: InnerXKey, 
{ pub origin: Option<(Fingerprint, DerivationPath)>, pub xkey: K, pub derivation_path: DerivationPath, pub wildcard: Wildcard, }
Expand description

An extended key with origin, derivation path, and wildcard.

Fields

origin: Option<(Fingerprint, DerivationPath)>

Origin information

xkey: K

The extended key

derivation_path: DerivationPath

The derivation path

wildcard: Wildcard

Whether the descriptor is wildcard

Implementations

Compares this key with a keysource and returns the matching derivation path, if any.

For keys that have an origin, the keysource’s fingerprint will be compared with the origin’s fingerprint, and the keysource’s path will be compared with the concatenation of the origin’s and key’s paths.

If the key wildcard, the last item of the keysource’s path will be ignored,
