Struct DefaultSecurePRNG 

pub struct DefaultSecurePRNG { /* private fields */ }

The recommended PRNGenerator PRNG for cryptographically secure purposes.

At the moment it uses ChaCha<20> as an underlying PRNG.

impl PartialEq for DefaultSecurePRNG

fn eq(&self, other: &DefaultSecurePRNG) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
