Struct UnifiedSpendingKey 

Source 
pub struct UnifiedSpendingKey { /* private fields */ }
Expand description

A set of spending keys that are all associated with a single ZIP-0032 account identifier.

With the zeroize feature, the Sapling and Orchard spending keys are erased from memory when this key is dropped. The transparent spending key is not erased.

Implementations§

Source§

impl UnifiedSpendingKey

Source

pub fn from_seed<P>( _params: &P, seed: &[u8], _account: AccountId, ) -> Result<UnifiedSpendingKey, DerivationError>
where P: Parameters,

Source

pub fn to_unified_full_viewing_key(&self) -> UnifiedFullViewingKey

Source

pub fn transparent(&self) -> &AccountPrivKey

Available on crate feature transparent-inputs only.

Returns the transparent component of the unified key at the BIP44 path m/44'/<coin_type>'/<account>'.

Source

pub fn sapling(&self) -> &ExtendedSpendingKey

Available on crate feature sapling only.

Returns the Sapling extended spending key component of this unified spending key.

Source

pub fn orchard(&self) -> &SpendingKey

Available on crate feature orchard only.

Returns the Orchard spending key component of this unified spending key.

Source

pub fn to_bytes(&self, era: Era) -> Secret<Vec<u8>>

Available on crate feature unstable only.

Returns a binary encoding of this key suitable for decoding with Self::from_bytes.

The encoded form of a unified spending key is only intended for use within wallets when required for storage and/or crossing FFI boundaries; unified spending keys should not be exposed to users, and consequently no string-based encoding is defined. This encoding does not include any internal validation metadata (such as checksums) as keys decoded from this form will necessarily be validated when the attempt is made to spend a note that they have authority for.

Source

pub fn from_bytes( era: Era, encoded: &[u8], ) -> Result<UnifiedSpendingKey, DecodingError>

Available on crate feature unstable only.

Decodes a UnifiedSpendingKey value from its serialized representation.

See Self::to_bytes for additional detail about the encoded form.

Source

pub fn default_address( &self, request: UnifiedAddressRequest, ) -> (UnifiedAddress, DiversifierIndex)

Available on crate features test-dependencies only.

Returns the unified address corresponding to the smallest valid diversifier index, along with that diversifier index.

See UnifiedFullViewingKey::default_address for additional details.

Source

pub fn default_transparent_address( &self, ) -> (TransparentAddress, NonHardenedChildIndex)

Available on crate feature transparent-inputs and (crate features test-dependencies) only.

Returns the default external transparent address using the transparent account pubkey.

See ExternalIvk::default_address for more information.
