Struct cap_rand::rngs::OsRng

pub struct OsRng(_);

A random number generator that retrieves randomness from from the operating system.

This corresponds to rand::rngs::OsRng, except instead of implementing Default it has an ambient-authority default function to access the operating system.

Implementations

impl OsRng

pub const fn default(ambient_authority: AmbientAuthority) -> Self

Returns an OsRng instance.
