Trait SieveFactory

pub trait SieveFactory {
    type Item;
    type Sieve: Iterator<Item = Self::Item>;

    // Required method
    fn make_sieve(
        &mut self,
        rng: &mut (impl CryptoRngCore + ?Sized),
        previous_sieve: Option<&Self::Sieve>,
    ) -> Option<Self::Sieve>;
}

A type producing sieves for random prime generation.

Required Associated Types

type Item

The type of items returning by the sieves.

type Sieve: Iterator<Item = Self::Item>

The resulting sieve.

Required Methods

fn make_sieve( &mut self, rng: &mut (impl CryptoRngCore + ?Sized), previous_sieve: Option<&Self::Sieve>, ) -> Option<Self::Sieve>

Makes a sieve given an RNG and the previous exhausted sieve (if any).

Returning None signals that the prime generation should stop.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
