Struct CapRng

Source

pub struct CapRng { /* private fields */ }

Expand description

The type returned by thread_rng, essentially just a reference to a PRNG in memory.

This corresponds to rand::rngs::ThreadRng, except that it isn’t tied to thread-local memory.

Implementations§

Source §

impl CapRng

Source

pub fn default(ambient_authority: AmbientAuthority) -> Self
