Struct ViewingKey 

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

A Sapling viewing key: the spend validating key ak and the nullifier deriving key nk.

The incoming viewing key derived from a ViewingKey is never zero.

Implementations§

Source§

impl ViewingKey

Source

pub fn from_parts( ak: SpendValidatingKey, nk: NullifierDerivingKey, ) -> Option<Self>

Constructs a viewing key from its components.

Returns None if the incoming viewing key derived from ak and nk is zero. Such a key is invalid and has no payment addresses.

Source

pub fn ak(&self) -> &SpendValidatingKey

Returns the spend validating key.

Source

pub fn nk(&self) -> &NullifierDerivingKey

Returns the nullifier deriving key.

Source

pub fn rk(&self, ar: Fr) -> VerificationKey<SpendAuth>

Source

pub fn ivk(&self) -> SaplingIvk
