Trait PRStream 

pub trait PRStream:
    Sized
    + Clone
    + ReprC {
    // Required method
    unsafe fn fill_raw(&mut self, dst_ptr: *mut u8, dst_len: usize);

    // Provided methods
    fn fill_block(&mut self, block: &mut [u8]) { ... }
    fn next_block<const N: usize>(&mut self) -> [u8; N] { ... }
}

Represents a pseudo random stream. These are easily convertible into PRNGs through the StreamPRNG wrapper.

Required Methods

unsafe fn fill_raw(&mut self, dst_ptr: *mut u8, dst_len: usize)

Fills the given raw buffer with randomness.

Safety

This function assumes that both dst_ptr and dst_len correspond to valid chunk of memory. Otherwise the behaviour is undefined.

Provided Methods

fn fill_block(&mut self, block: &mut [u8])

Fills the given block with randomness.

fn next_block<const N: usize>(&mut self) -> [u8; N]

Generates the next block of given length.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
