Struct dkg_gadget::async_protocols::OfflinePartyId

pub struct OfflinePartyId(_);

A Offline Party Id, in the range [1, t+1], where t is the signing threshold.

This is a wrapper around u16 to prevent the misuse of the party id as a keygen party id, for example.

To construct a OfflinePartyId, use the Self::try_from_keygen_party_id method.

Implementations

impl OfflinePartyId

pub fn try_from_keygen_party_id( i: KeygenPartyId, s_l: &[KeygenPartyId] ) -> Result<Self, DKGError>

Creates a OfflinePartyId from a KeygenPartyId and a list of the signing parties.

This finds the index of the KeygenPartyId in the list of signing parties, then we use that index as OfflinePartyId.

This is safe because the KeygenPartyId is guaranteed to be in the range [1, n], and the OfflinePartyId is guaranteed to be in the range [1, t+1]. if the KeygenPartyId is not in the list of signing parties, then we return an error.

pub fn try_to_keygen_party_id( &self, s_l: &[KeygenPartyId] ) -> Result<KeygenPartyId, DKGError>

Tries to Converts the OfflinePartyId to a KeygenPartyId.

Returns an error if the OfflinePartyId is not in the list of signing parties.

pub const fn to_index(&self) -> usize

Converts the OfflinePartyId to an index.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
