Struct bc_crypto::SecureRandomNumberGenerator

pub struct SecureRandomNumberGenerator;

A random number generator that can be used as a source of cryptographically-strong randomness.

Trait Implementations

impl RandomNumberGenerator for SecureRandomNumberGenerator

fn next_u64(&mut self) -> u64

Returns the next random u64.

fn random_data(&mut self, size: usize) -> Vec<u8>

Returns a vector of random bytes of the given size.

fn fill_random_data(&mut self, data: &mut [u8])

Fills the given buffer with random bytes.

fn next_with_upper_bound<T>(&mut self, upper_bound: T) -> Twhere T: PrimInt + Unsigned + NumCast + FromPrimitive + AsPrimitive<u128> + OverflowingMul + Shl<usize, Output = T> + Shr<usize, Output = T> + WrappingSub + OverflowingAdd + Widening,

Returns a random value that is less than the given upper bound.

fn next_in_range<T>(&mut self, range: &Range<T>) -> Twhere T: PrimInt + FromPrimitive + AsPrimitive<u128> + OverflowingMul + Shl<usize, Output = T> + Shr<usize, Output = T> + HasMagnitude + OverflowingAdd,

Returns a random value within the specified range, using the given generator as a source for randomness.

fn next_in_closed_range<T>(&mut self, range: &RangeInclusive<T>) -> Twhere T: PrimInt + FromPrimitive + AsPrimitive<u128> + OverflowingMul + Shl<usize, Output = T> + Shr<usize, Output = T> + HasMagnitude,
