Implementations§

Source§

impl<C: Ciphersuite> ThresholdView<C>

Source

pub fn scalar(&self) -> C::F

Return the scalar applied to this view.

Source

pub fn offset(&self) -> C::F

Return the offset applied to this view.

Source

pub fn group_key(&self) -> C::G

Return the group key.

Source

pub fn included(&self) -> &[Participant]

Return the included signers.

Source

pub fn interpolation_factor(&self, participant: Participant) -> Option<C::F>

Return the interpolation factor for a signer.

Source

pub fn secret_share(&self) -> &Zeroizing<C::F>

Return the interpolated secret share, with the expected linear combination taken.

Source

pub fn original_verification_share(&self, l: Participant) -> C::G

Return the original (untweaked) verification share for the specified participant.

This will panic if the participant index is invalid for these keys.

Source

pub fn verification_share(&self, l: Participant) -> C::G

Return the interpolated verification share, with the expected linear combination taken, for the specified participant.

This will panic if the participant was not included in the signing set.
