Struct PprfConfig

pub struct PprfConfig { /* private fields */ }

Config for a PPRF expansion.

Implementations

impl PprfConfig

pub fn new(domain: usize, pnt_count: usize) -> Self

Create a PprfConfig

Panics

• if domain < 2
• if domain % 2 != 0
• if pnt_count % PARALLEL_TREES != 0

pub fn base_ot_count(&self) -> usize

Number of base OTs needed for the configured PPRF expansion.

pub fn pnt_count(&self) -> usize

pub fn domain(&self) -> usize

pub fn depth(&self) -> usize

pub fn size(&self) -> usize

pub fn sample_choice_bits<R: RngCore + CryptoRng>(&self, rng: &mut R) -> Vec<u8>

Base OT choice bits needed for this PPRF expansion.

Every u8 element is either 0 or 1.

pub fn get_points(&self, out_fmt: OutFormat, base_choices: &[u8]) -> Vec<usize>

Trait Implementations

impl Clone for PprfConfig

fn clone(&self) -> PprfConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PprfConfig

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

Formats the value using the given formatter.

impl PartialEq for PprfConfig

fn eq(&self, other: &PprfConfig) -> 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.
