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", so this trait is not object safe.
