Struct PartialSsaShare 

Source 
pub struct PartialSsaShare<S: PixSpec>(pub(crate) <PixScalar<S> as PrimeField>::Repr);
Expand description

Share of a polynomial used to reconstruct a portion of the Session Stealth Address (SSA).

This corresponds to the P_ij(X) of the polynomial used to reconstruct the j-th portion of i-th SSA at some value X.

The struct does not hold the X value, as it is usually computed from the nonce.

See TaggedEncryptedPartialSsaShare and EncryptedPartialSsaShare for more details.
