Struct frost_core::frost::Identifier

pub struct Identifier<C: Ciphersuite>(_);

A FROST participant identifier.

The identifier is a field element in the scalar field that the secret polynomial is defined over, corresponding to some x-coordinate for a polynomial f(x) = y. MUST NOT be zero in the field, as f(0) = the shared secret.

Implementations

impl<C> Identifier<C>where C: Ciphersuite,

pub fn serialize(&self) -> <<C::Group as Group>::Field as Field>::Serialization

Serialize the identifier using the ciphersuite encoding.

pub fn deserialize( buf: &<<C::Group as Group>::Field as Field>::Serialization ) -> Result<Self, Error<C>>

Deserialize an Identifier from a serialized buffer. Returns an error if it attempts to deserialize zero.

Trait Implementations

fn mul_assign(&mut self, identifier: Identifier<C>)

Performs the *= operation.

impl<C> Ord for Identifier<C>where C: Ciphersuite,

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.
