Struct Label 

pub struct Label { /* private fields */ }

Silent Payment label for deriving multiple addresses.

Labels allow a receiver to have multiple distinct addresses from a single Silent Payment address, useful for:

• Separating payments by purpose
• Identifying payment sources
• Organizing incoming funds

Implementations

impl Label

pub fn new(index: u32) -> Self

Create a new label from index.

pub fn index(&self) -> u32

Get the label index.

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

Get the label tweak.

pub fn apply_to_pubkey(&self, spend_pubkey: &[u8; 33]) -> Result<[u8; 33]>

Apply label to a spend public key.

Returns B_m = B_spend + label * G

pub fn apply_to_privkey(&self, spend_privkey: &[u8; 32]) -> Result<[u8; 32]>

Apply label to a spend private key.

Returns b_m = b_spend + label

Trait Implementations

impl Clone for Label

fn clone(&self) -> Label

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Label

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Label

fn eq(&self, other: &Label) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
