Trait RngCore 

pub trait RngCore {
    // Required method
    fn try_fill_bytes(&mut self, destination: &mut [u8]) -> Result<(), Error>;

    // Provided methods
    fn next_u32(&mut self) -> u32 { ... }
    fn next_u64(&mut self) -> u64 { ... }
    fn fill_bytes(&mut self, destination: &mut [u8]) { ... }
}

The byte-oriented randomness interface used by dcrypt.

Required Methods

fn try_fill_bytes(&mut self, destination: &mut [u8]) -> Result<(), Error>

Fill destination, propagating failures from the caller’s entropy source rather than silently substituting weak randomness.

Provided Methods

fn next_u32(&mut self) -> u32

fn next_u64(&mut self) -> u64

fn fill_bytes(&mut self, destination: &mut [u8])

Dyn Compatibility

This trait is dyn compatible.

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