Struct Note 

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

A discrete amount of funds received by an address.

Implementations§

Source§

impl Note

Source

pub fn from_parts( recipient: Address, value: NoteValue, rho: Rho, rseed: RandomSeed, ) -> CtOption<Self>

Creates a Note from its component parts.

Returns None if a valid NoteCommitment cannot be derived from the note.

§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.

Source

pub fn recipient(&self) -> Address

Returns the recipient of this note.

Source

pub fn value(&self) -> NoteValue

Returns the value of this note.

Source

pub fn rseed(&self) -> &RandomSeed

Returns the rseed value of this note.

Source

pub fn rho(&self) -> Rho

Returns rho of this note.

Source

pub fn commitment(&self) -> NoteCommitment

Derives the commitment to this note.

Defined in Zcash Protocol Spec § 3.2: Notes.

Source

pub fn nullifier(&self, fvk: &FullViewingKey) -> Nullifier

Derives the nullifier for this note.
