Struct OsNonceSource 

pub struct OsNonceSource;

OS-backed nonce source. On tier-1-kms / tier-2-multi-kms this pulls from the underlying AEAD crate’s default RNG hook (itself getrandom-backed). On the default feature set it is still constructible — encryption paths reject before the nonce source is consulted.

Trait Implementations

impl Clone for OsNonceSource

fn clone(&self) -> OsNonceSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OsNonceSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for OsNonceSource

fn default() -> OsNonceSource

Returns the “default value” for a type.

impl NonceSource for OsNonceSource

fn fill(&self, out: &mut [u8])

Fill out with len fresh nonce bytes. len matches NonceBytes::expected_len for the active AEAD kind; panics / short writes are illegal — return an error via the caller’s wrapper if needed.

impl Copy for OsNonceSource
