Struct DiscreteLog

pub struct DiscreteLog {
    pub generator: RistrettoPoint,
    pub target: RistrettoPoint,
    /* private fields */
}

Type that captures a discrete log challenge.

The goal of discrete log is to find x such that x * generator = target.

Fields

generator: RistrettoPoint

Generator point for discrete log

target: RistrettoPoint

Target point for discrete log

Implementations

impl DiscreteLog

Solves the discrete log instance using a 16/16 bit offline/online split

pub fn new(generator: RistrettoPoint, target: RistrettoPoint) -> Self

Discrete log instance constructor.

Default number of threads set to 1.

pub fn num_threads( &mut self, num_threads: NonZeroUsize, ) -> Result<(), DiscreteLogError>

Adjusts number of threads in a discrete log instance.

pub fn set_compression_batch_size( &mut self, compression_batch_size: NonZeroUsize, ) -> Result<(), DiscreteLogError>

Adjusts inversion batch size in a discrete log instance.

pub fn decode_u32(self) -> Option<u64>

Solves the discrete log problem under the assumption that the solution is a positive 32-bit number.

Trait Implementations

impl Clone for DiscreteLog

fn clone(&self) -> DiscreteLog

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiscreteLog

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DiscreteLog

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DiscreteLog

fn eq(&self, other: &DiscreteLog) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DiscreteLog

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
