Expand description

The ZIP 32 derivation path at which a key can be found.

Implementations§

Source§

impl Zip32Derivation

Source

pub fn parse( seed_fingerprint: [u8; 32], derivation_path: Vec<u32>, ) -> Result<Self, ParseError>

Parses a ZIP 32 derivation path from its component parts.

Returns an error if any of the derivation path indices are non-hardened (which this crate does not support, even though Sapling does).

Source§

impl Zip32Derivation

Source

pub fn seed_fingerprint(&self) -> &[u8; 32]

The ZIP 32 seed fingerprint.

Source

pub fn derivation_path(&self) -> &Vec<ChildIndex>

The sequence of indices corresponding to the shielded HD path.

Source§

impl Zip32Derivation

Source

pub fn extract_account_index( &self, seed_fp: &SeedFingerprint, expected_coin_type: ChildIndex, ) -> Option<AccountId>

Extracts the ZIP 32 account index from this derivation path.

Returns None if the seed fingerprints don’t match, or if this is a non-standard derivation path.
