Struct cap_rand::rngs::OsRng

source · [−]

pub struct OsRng(_);

Expand description

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

source

impl OsRng

source

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

Returns an OsRng instance.

Ambient Authority

This function makes use of ambient authority to access the platform entropy source.
