Struct sapling_crypto::note::Note
source · pub struct Note { /* private fields */ }
Expand description
A discrete amount of funds received by an address.
Implementations§
source§impl Note
impl Note
sourcepub fn from_parts(
recipient: PaymentAddress,
value: NoteValue,
rseed: Rseed
) -> Self
pub fn from_parts( recipient: PaymentAddress, value: NoteValue, rseed: Rseed ) -> Self
Creates a note from its component parts.
§Caveats
This low-level constructor enforces that the provided arguments produce an
internally valid Note
. However, it allows notes to be constructed in a way that
violates required security checks for note decryption, as specified in
Section 4.19 of the Zcash Protocol Specification. Users of this constructor
should only call it with note components that have been fully validated by
decrypting a received note according to Section 4.19.
sourcepub fn recipient(&self) -> PaymentAddress
pub fn recipient(&self) -> PaymentAddress
Returns the recipient of this note.
sourcepub fn nf(&self, nk: &NullifierDerivingKey, position: u64) -> Nullifier
pub fn nf(&self, nk: &NullifierDerivingKey, position: u64) -> Nullifier
Computes the nullifier given the nullifier deriving key and note position
sourcepub fn cmu(&self) -> ExtractedNoteCommitment
pub fn cmu(&self) -> ExtractedNoteCommitment
Computes the note commitment
sourcepub fn generate_or_derive_esk<R: RngCore + CryptoRng>(
&self,
rng: &mut R
) -> EphemeralSecretKey
pub fn generate_or_derive_esk<R: RngCore + CryptoRng>( &self, rng: &mut R ) -> EphemeralSecretKey
Derives esk
from the internal Rseed
value, or generates a random value if this
note was created with a v1 (i.e. pre-ZIP 212) note plaintext.
