Struct PaymentAddress

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

A Sapling payment address.

§Invariants

  • diversifier is guaranteed to be valid for Sapling (only 50% of diversifiers are).
  • pk_d is guaranteed to be prime-order (i.e. in the prime-order subgroup of Jubjub, and not the identity).

Implementations§

Source§

impl PaymentAddress

Source

pub fn from_parts( diversifier: Diversifier, pk_d: DiversifiedTransmissionKey, ) -> Option<Self>

Constructs a PaymentAddress from a diversifier and a Jubjub point.

Returns None if diversifier is not valid for Sapling, or pk_d is the identity. Note that we cannot verify in this constructor that pk_d is derived from diversifier, so addresses for which these values have no known relationship (and therefore no-one can receive funds at them) can still be constructed.

Source

pub fn from_bytes(bytes: &[u8; 43]) -> Option<Self>

Parses a PaymentAddress from bytes.

Source

pub fn to_bytes(&self) -> [u8; 43]

Returns the byte encoding of this PaymentAddress.

Source

pub fn diversifier(&self) -> &Diversifier

Returns the Diversifier for this PaymentAddress.

Source

pub fn pk_d(&self) -> &DiversifiedTransmissionKey

Returns pk_d for this PaymentAddress.

Source

pub fn create_note(&self, value: NoteValue, rseed: Rseed) -> Note
