Struct ring::aead::Nonce

pub struct Nonce(/* private fields */);

A nonce for a single AEAD opening or sealing operation.

The user must ensure, for a particular key, that each nonce is unique.

Nonce intentionally doesn’t implement Clone to ensure that each one is consumed at most once.

Implementations

impl Nonce

pub fn try_assume_unique_for_key(value: &[u8]) -> Result<Self, Unspecified>

Constructs a Nonce with the given value, assuming that the value is unique for the lifetime of the key it is being used with.

Fails if value isn’t NONCE_LEN bytes long.

pub fn assume_unique_for_key(value: [u8; 12]) -> Self

Constructs a Nonce with the given value, assuming that the value is unique for the lifetime of the key it is being used with.

Trait Implementations

impl AsRef<[u8; 12]> for Nonce

fn as_ref(&self) -> &[u8; 12]

Converts this type into a shared reference of the (usually inferred) input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
